Astroswitches

The Astroswitches (アストロスイッチ) are mysterious devices that are the source of Kamen Rider Fourze's powers. They are infused with Cosmic Energy to materialize armaments known as the Fourze Modules (フォーゼモジュール). Ten of them at a time can be carried in the Astroswitch Kaban. They can also be used to operate Foodroids as well as serve as power-ups for Kamen Rider Meteor.

There are 40 known normal Astroswitches in total, 10 of which each correspond to one of the attachment ports on Kamen Rider Fourze's limbs, known as Module Basements (モジュールベイスメント).
 * Circle Module Basement (サークルモジュールベイスメント): Right Arm. Circle Astroswitches in nature tend to be close-combat weapons, as well as having the capacity to change Fourze's States if its number is a multiple of 10.
 * Cross Module Basement (クロスモジュールベイスメント): Right Leg. Cross Astroswitches in nature tend to be mid-ranged weaponry.
 * Triangle Module Basement (トライアングルモジュールベイスメント): Left Leg. Triangle Astroswitches in nature tend to be themed after transport.
 * Square Module Basement (スクエアモジュールベイスメント): Left Arm. Square Astroswitches in nature tend to be battle-support items.

Background
Rokuro originally developed the Astroswitches from studying the Core Switch (コアスイッチ), a mysterious crystal-like Switch that the alien race known as the Presenters sent to Earth's moon in hopes that humanity would reverse engineer their Cosmic Energy-power technology so contact between the two races can be made. Compared to Gamou's Zodiarts Switches designed to force evolve human users, the Astroswitches Rokuro designed were devised to enable the user of the Fourze Driver to safely transverse the cosmos. Though thought to been destroyed when the OSTO base exploded, the Core Switch produced a Core Child prior to the event that would complete the Fourze System and return to the Presenters with it.

Fourze's Switches

 * 1) Rocket Switch (ロケットスイッチ): The Rocket Switch arms Fourze with the Rocket Module (ロケットモジュール) on his right arm, allowing him to fly. By using the exhaust ports on the Rocket Module, Fourze can add 40 additional tons to his punches. He had the inital problem of unable to control the Rocket Module's ports. First used in Kamen Rider OOO WONDERFUL: The Shogun and the 21 Core Medals.
 * 2) Launcher Switch (ランチャースイッチ): The Launcher Switch arms Fourze with the Launcher Module (ランチャーモジュール) on his right leg, allowing him to attack enemies from a far distance. The module can launch 5 missiles to attack an enemy, though with improper handling, the flight pattern of the missiles can be very chaotic. During the Aries Zodiarts incident, this Astroswitch was rendered useless after Aries cuts it off from the Fourze System by making Fourze's leg go to "sleep".
 * 3) Drill Switch (ドリルスイッチ): The Drill Switch arms Fourze with the Drill Module (ドリルモジュール) on his left leg, allowing him to drill through the ground and pierce enemies with a powerful kick, though it limits his movements. It spins around 200 RPM.
 * 4) Radar Switch (レーダースイッチ): The Radar Switch arms Fourze with the Radar Module (レーダーモジュール) on his left arm, allowing him to detect any enemies that are not visible and reflect certain waves, as well as make contact with Kengo from the Rabbit Hutch. The module can also be used with the Launcher Module to launch very precise homing missiles. First used in Kamen Rider OOO WONDERFUL: The Shogun and the 21 Core Medals.
 * 5) Magic Hand Switch (マジックハンドスイッチ): The Magic Hand Switch arms Fourze with the Magic Hand Module (マジックハンドモジュール) on his right arm allowing him to use a large manipulator arm which gives him an extra 10 meters of reach and pick up heavy objects using the End Effect Pinch (エンドエフェクトペンチ). First used in Kamen Rider OOO WONDERFUL: The Shogun and the 21 Core Medals.
 * 6) Camera Switch (カメラスイッチ): The Camera Switch arms Fourze with the Camera Module (カメラモジュール) on his left arm, allowing him to view far distances and see things that normally isn't noticed. It can also receive data from the environment nearby. The Camera Switch is generally used to operate the Burgermeal, though it is implied there are other Burgermeals being look out without the use of the Camera Switch. Also, the Module is more powerful than a Burgermeal.
 * 7) Parachute Switch (パラシュートスイッチ): The Parachute Switch arms Fourze with the Parachute Module (パラシュートモジュール) on his left arm, allowing him to deploy three parachutes to land safely to the ground if in free-fall from a significant height. When the parachutes are not in use, they are stored in the dark green box on Kamen Rider Fourze's arm.
 * 8) Chainsaw Switch (チェーンソースイッチ): The Chainsaw switch arms Fourze with the Chainsaw Module (チェーンソーモジュール) on his right leg, allowing him to use the saw on his foot that has a powerful engine that can rotate the blade up to 15,000 rounds per minute, cutting into even the toughest of Zodiarts armor. Because the blade is on the foot, maneuverability is an issue to make sure Fourze doesn't cut himself.
 * 9) Hopping Switch (ホッピングスイッチ): The Hopping Switch arms Fourze with the pogo stick-like Hopping Module (ホッピングモジュール) on his left leg, allowing him to to significantly increase his maximum jumping height from 20 meters to 40 meters. However, this Module is unpredictable and great control is needed to use this Module properly.
 * 10) Elek Switch (エレキスイッチ): The Elek Switch arms Fourze with the Elek Module Billy the Rod. Initially, it just changed his right forearm's color to gold and armed him with just Billy the Rod and suffered backlash shock from the power, but after allowing the Elek Switch's power to course into Fourze's body, it allows Fourze to assume Elek States.
 * 11) Scissors Switch (シザーススイッチ): The Scissors Switch arms Fourze with the arts-and-crafts-looking Scissors Module (シザースモジュール) on his left arm, which allows him to cut though even metal. If the second opening of the show is any indication, it can also fire a pulse of energy for a long-range attack. The Scissors Switch is generally used to operate the Potechokin.
 * 12) Beat Switch (ビートスイッチ): The Beat Switch arms Fourze with the Beat Module (ビートモジュール) on his right leg, resembling a small subwoofer that can produce sonic waves with a range of 20Hz-5kHz and a tweeter with a range of 5kHz-24kHz. A rather hilarious aspect of the Beat Module is that it can behave much like a normal sub-woofer, meaning that electric guitars could be plugged into it.
 * 13) Chain Array Switch (チェーンアレイスイッチ): The Chain Array Switch arms Fourze with the Chain Array Module (チェーンアレイモジュール) on his right arm, which is a glorified spiked flail. The steel ball on the end of the chain is called the Blowing Star (ブローイングスター), weighing about 120 kg. The Rough Spikers (ラフスパイカー) on the Blowing Star are made from a newly discovered metal known as Astorium (アストリウム<). It seems old-fashioned and low-tech, but it gets the job done in handling Zodiarts. The Chain Array's links can also stretch. Like any chained weapon, inertia is a factor to make sure Fourze doesn't end up smacking the Module into himself, and there is also the chance of the Module being reflected back onto Fourze.
 * 14) Smoke Switch (スモークスイッチ): The Smoke Switch arms Fourze with the Smoke Module (スモークモジュール), allowing him to emit smoke within a 5 mile radius for 5 minutes which can obstruct an opponent's vision in close combat, not to mention disorientate said opponent from the choking smoke.
 * 15) Spike Switch (スパイクスイッチ): The Spike Switch arms Fourze with the leg-brace of the Spike Module (スパイクモジュール) on his left leg, giving Kamen Rider Fourze an advantage in close-range kicks. The Spike Module consists of Rough Spikers, again made out of Astorium, only they extend a good two feet seconds before impact for maximum damage/penetration. It is also quite heavy, as Fourze had to use both arms to lift his leg out of a foot-deep hole speculated to be caused by the Spike Module, as it happened off-screen.
 * 16) Winch Switch (ウインチスイッチ): The Winch Switch arms Fourze with the drum-style Winch Module (ウインチモジュール) on his left arm, which has a spinning turbine. The Winch Module's Boost Hooker (ブーストフッカー) shoots out at high speed and can pull objects with up to 5 tons.
 * 17) Flash Switch (フラッシュスイッチ): The Flash Switch arms Fourze with the Flash Module (フラッシュモジュール) on his right arm, allowing Kamen Rider Fourze to blind enemies (or anybody else for that matter, including himself) with the light of the sun at full power. Fourze can also control the intensity of the Flash Module's light, so he can use it like a flashlight. The Flash Switch is generally used for the Flashake Foodroid.
 * 18) Shield Switch (シールドスイッチ): The Shield Switch arms Fourze with the Lockheed Martin X-33-looking Shield Module (シールドモジュール) on his left arm, allowing him to protect himself from any attack, though it is rather small in size. The Shield Module is also made from Astorium. Despite this, the Shield Module was rendered useless in future fights with the Cancer Zodiarts, as it's claw arm cleaved the Module in half.
 * 19) Gatling Switch (ガトリングスイッチ): The Gatling Switch arms Fourze with the Gatling Module (ガトリングモジュール) on his left leg, allowing Kamen Rider Fourze to shoot 10 rounds per second. The bullets have enough power to pierce into concrete.
 * 20) Fire Switch (ファイアースイッチ): The Fire Switch allows Fourze to enter Fire States and arms him with the Fire Module Hee-Hackgun. Having learned from the Elek Switch, Fourze had no problem accessing Fire States. The Fire Switch's dormant ability is to absorb heat-based attacks to enhance it's own.
 * 21) Stealth Switch (ステルススイッチ): The Stealth Switch arms Fourze with the Lockheed F-117 Nighthawk-looking Stealth Module (ステルスモジュール) on his right leg, allowing Fourze to become invisible for 5 seconds. It works by absorbing reflected light off of the Fourze System.
 * 22) Hammer Switch (ハンマースイッチ): The Hammer Switch arms Fourze with the squeaky hammer-looking Hammer Module (ハンマーモジュール) on his left arm (though the majority of the Module covers only his hand), allowing Fourze to do incredible damage with it. He can also slam the Module onto the ground to make a shock wave travel through the ground to floor a Zodiarts. However, if the Hammer Module hits something that's too hard to hit, the shock wave instead travels backwards, harming the user. During the Aries Zodiarts incident, this Astroswitch was rendered useless after Aries cuts it off from the Fourze System by making Fourze's arm go to "sleep".
 * 23) Water Switch (ウォータースイッチ): The Water Switch arms Kamen Rider Fourze with the faucet-looking Water Module (ウォーターモジュール) on his left leg, allowing him to shoot intense streams of water from the nozzle for ranged attacks.
 * 24) Medical Switch (メディカルスイッチ): The Medical Switch arms Kamen Rider Fourze with the med-kit looking Medical Module (メディカルモジュール) on his left arm, which gives him access to various medicines made from Cosmic Energy.
 * 25) Pen Switch (ペンスイッチ): The Pen Switch arms Kamen Rider Fourze with the calligraphy brush-looking Pen Module (ペンモジュール) on his right leg. When swung, Fourze can make three-dimensional objects on any surface from the "ink", which can serve as either improvised shields or to reveal invisible enemies after the ink hits it's mark. What the material the solidifed "ink" is made of is none other than pure carbon. It has a Limit Break, where Fourze covers the foe in the Pen Switch's ink to disable any special abilities a Zodiarts might have.
 * 26) Wheel Switch (ホイールスイッチ): The Wheel Switch arms Kamen Rider Fourze with the Wheel Module (ホイールモジュール) on his left leg, which gives him two wheels akin to a Segway to allow him to move at high speeds without straining himself or getting the Masshingler. It can also run up walls.
 * 27) Screw Switch (スクリュースイッチ): The Screw Switch arms Kamen Rider Fourze with the submarine-like Screw Module (スクリューモジュール) on his left leg, allowing him to propel himself underwater without tiring himself out.
 * 28) Hand Switch (ハンドスイッチ): The Hand Switch arms Kamen Rider Fourze with the Hand Module (ハンドモジュール) on his right leg, allowing him to utilize another manipulator arm, this time being used for delicate things. With concentration, the Hand Module can disassemble stuff.
 * 29) Schop Switch (スコップスイッチ): The Schop Switch arms Kamen Rider Fourze with the power shovel-like Schop Module (スコップモジュール) on his right arm, allowing him to dig into the ground with ease, as well as lift an incredible amount of dirt to bury a target in a giant mound of dirt. The Schop Switch is generally used to operate the Horuwankov Foodroid.
 * 30) N Magnet Switch (Nマグネットスイッチ): The N Magnet Switch is built into the MagPhone along with the S Magnet Switch, which allows Kamen Rider Fourze to become Magnet States. The N Magnet Switch, when used by itself, allows Kamen Rider Fourze to use the giant red-colored, north pole aligned, magnet bar-like N Magnet Module (Nマグネットモジュール) when it is not fully utilized. The N Magnet Module has a very powerful magnetic field, thus any metal object that can be magnetized will be attracted to Fourze's body. If the S Magnet Module is active, the N Magnet Module will be attracted and form unintentional cuffs. After it has been modified into the NS MagPhone with the S Magnet Switch, Fourze is able to control the Module and also changes into the powerful Magnet States.
 * 31) S Magnet Switch (Sマグネットスイッチ): The S Magnet Switch is built into the MagPhone along with the N Magnet Switch, which allows Kamen Rider Fourze to assume Magnet States. The S Magnet Switch, when used by itself, allows Kamen Rider Fourze to use the giant blue-colored, south pole aligned, magnet bar-like S Magnet Module (Sマグネットモジュール) when it is not fully utilized. The S Magnet Module has a very powerful magnetic field, thus any metal object that can be magnetized will be attracted to Fourze's body. If the N Magnet Module is active, the S Magnet Module will be attracted and form unintentional cuffs. After it has been modified into the NS MagPhone with the N Magnet Switch, Fourze is able to control the Module and also changes into the powerful Magnet States.
 * 32) Freeze Switch (フリーズスイッチ): The Freeze Switch arms Kamen Rider Fourze with the refrigerator-like Freeze Module (フリーズモジュール) on his right leg, which allows him to emit super cold vapors to freeze liquids in a mere instant. It is generally used to operate the Softonya Foodroid.
 * 33) Claw Switch (クローモッチ): The Claw Switch arms Kamen Rider Fourze with the triclaw-like Claw Module (クローモジュール) on his right arm, allowing him to cleave into enemies. It can also serve as a decent shield against melee attacks.
 * 34) Board Switch (ボードスイッチ): The Board Switch arms Kamen Rider Fourze with the snowboard-like Board Module (ボードモジュール) on his left leg, which allows Fourze to travel on the ground with no resistance at all.
 * 35) Giantfoot Switch (ジャイアントフットスイッチ): The Giantfoot Switch arms Kamen Rider Fourze with the boot-like Giantfoot Module (ジャイアントフットモジュール) on his right leg. This Module has a peculiar power, which allows Fourze to focus and amplify gravity at a localized point to bring opponents down, by stomping his foot on the ground, or in later instances swinging it around. A mirage of the Giantfoot Module appears above the opponent as a side effect, making Kamen Rider Fourze seem like he is mentally creating a construct of Cosmic Energy to crush his opponents.
 * 36) Aero Switch (エアロスイッチ): The Aero Switch arms Kamen Rider Fourze with the turbine-like Aero Module (エアロモジュール) on his left leg, allowing him to suck in large quantities of air so it can then be pressurized and expelled to either lift Fourze off of the ground, or direct the pressurized air at a target to disorient it from the intense winds.
 * 37) Gyro Switch (ジャイロスイッチ): The Gyro Switch arms Kamen Rider Fourze with the helicopter rotor-like Gyro Module (ジャイロモジュール) on his left arm, allowing him to hover into the sky. Compared to the Rocket Module, another Module that grants flight, the Gyro Module has far greater handling and control, though scarifies speed at the same time. It is generally used to operate the Nuggegyroika.
 * 38) Net Switch (ネットスイッチ): The Net Switch arms Kamen Rider Fourze with the butterfly net-like Net Module (ネットモジュール) on his right leg, allowing him to create a electromagnetic net to scoop up incredibly tiny objects by swinging his leg. If the tiny objects turns out to be a Zodiarts, the net will recombine the broken-up pieces and force the Zodiarts to stay together, all while binding the arms together.
 * 39) Stamper Switch (スタンパースイッチ): The Stamper Switch arms Kamen Rider Fourze with the rubber stamp-like Stamper Module (スタンパーモジュール) on his left leg. How this Module works is first Fourze would kick a Zodiarts with the Stamper, the Module boosting his kicking damage when the hydrolics kick in, leaving a "stamp" of the Kamen Rider Club logo. The "stamp", after 15 seconds, explodes with a focused blast, doing additional damage.
 * 40) Cosmic Switch (コズミックスイッチ): The Cosmic Switch arms Kamen Rider Fourze with the Cosmic Module Barizun Sword. However, in it's first testing, the Switch would not even go into the Driver, and shorted out when Gentaro pressed the big red button it has one too many times, triggering an explosion. Once Gentaro was brought to life with this Switch, the Cosmic Swich allows Fourze to transform into Cosmic States.

Super Switches
Super Switches are Astroswitches similar to the original Switches but have more power, to the point of even allowing State Changes.
 * S-1. Rocket Switch Super-1 (ロケットスイッチスーパーワン): The Rocket Switch Super-1 allows Kamen Rider Fourze to use two Rocket Modules while assuming Rocket States. This special Switch is created by Kamen Rider Nadeshiko in desperation just prior to Kannagi converting her into the SOLU Switch. Even after Super Galaxy King's destruction and Nadeshiko leaving Earth as a sentient energy being, Gentaro kept the Rocket Switch Super-1 on his person. The Rocket Switch Super-1 is later used, along with the Drill Switch Super-3, to arm the two Rocket Modules to Go-BusterOh's arms.
 * S-3. Drill Switch Super-3 (ドリルスイッチスーパースリー): The Drill Switch Super-3 allows Kamen Rider Fourze to arm Go-BusterOh's legs with two Drill Modules. This special Switch was created by Kengo to be used along with the Rocket Switch Super-1. By using the Rocket Switch Super-1 and Drill Switch Super-3 together, it creates a link between the Fourze Driver and Go-BusterOh, the Go-Busters' MegaZord, arming it with giant versions of the Rocket and Drill Modules in a combination known as Rocket Drill Go-BusterOh. In theory, Drill Switch Super-3 should be also able to be used on its own by Fourze to access a new State form just as Rocket Switch Super-1, allowing Kamen Rider Fourze to use two Drill Modules in what would be called Drill States (ドリルステイツ). However, this form hasn't been seen.

Extra Switches

 * Gate Switch (ゲートスイッチ): The Gate Switch is an Astroswitch which allows Kengo to enter the Rabbit Hutch through the locker in an abandoned part of the AGHS campus. It is eventually revealed that Tachibana was the one who originally delivered the Switch to Kengo. The Gate Switch resembles a golden Launcher Switch, leading to a release of it, however, it was via a special campaign and was only avaliable by getting the first edition of the Fourze "Miracle Rider Box". The Gate Switch cannot be used by Kamen Rider Fourze.
 * Shin-chan Switch (しんちゃんスイッチ): The Shin-chan Switch is a special switch which appears during the crossover with Crayon Shin-chan that allows Kamen Rider Fourze to transition into "anime". The Switch also transforms Shin-chan into a Rocket which wraps around on Kamen Rider Fourze's waist, the design of the switch seems to be based on the Legend Rider Switches as the face of Shin-chan is the activation button like how the mask of the Rider in the Legend Rider Switch series is the activation button.
 * Yuki (ユウキ): The Yuki Switch is shown as a prize in the fictional Televi-kun issue that Ryusei purchases in Kamen Rider Fourze Special Bonus DVD: Astroswitch Secret Report.
 * Clear Drill Switch (クリアドリルスイッチ): The Clear Drill Switch is a mysterious Astroswitch resembling the Drill Switch which was created from the excess Cosmic Energy from Kamen Riders Fourze and OOO's battle with Super Gingaoh, manifesting as a replica of the Drill Switch before landing in the Amazon rain forest from space, which is later found by Kamen Rider Amazon who gives it to Gentaro. The Clear Drill Switch allows Fourze to combine the Rocket and Drill Modules to create the Rocket Drill Module and transform him into Rocket Drill States. It's likely that this switch is based on other clear switches that can be found in special magazines or capsule machines.
 * Fusion Switch (フュージョンスイッチ): The Fusion Switch is a special, purple globe-looking Switch that allows Fourze to use the Meteor Switch to combine his powers with those of Kamen Rider Meteor and assumes Meteor Fusion States, a purple and gold, evolved version of Cosmic States and has similarities with Meteor Storm as well. The switch was created using data compiled from XVII and is charged up by the friendship energies of the forty people Gentarou's life touched and those people throwing the forty Astroswitches on at the same time. The Fusion Switch appears in Kamen Rider Fourze the Movie: Everyone, Space is Here!. It reappears in Kamen Rider × Kamen Rider Wizard & Fourze: Movie War Ultimatum, where Fourze uses it to combine Meteor and Nadeshiko's powers with his own to create Meteor Nadeshiko Fusion States.
 * Clear Launcher (クリアランチャー): The Clear Launcher Switch is an enhanced version of the Launcher Switch when Kamen Rider Fourze becomes Meteor Fusion States.
 * Nadeshiko Switch (なでしこスイッチ): The Nadeshiko Switch is a silver and metallic blue-colored Astroswitch that contains Kamen Rider Nadeshiko's power and allows Fourze to assume Meteor Nadeshiko Fusion States when used with the Meteor and Fusion Switches. When in used, it gives Fourze the ski-like Hovering Lifter Modules. It's a silver recolor of the Launcher Switch.

Meteor's Switches

 * The Meteor Switch (メテオスイッチ) owned by Ryusei, used to transform into Kamen Rider Meteor. It can also be used as a communication device to the M-BUS satellite to contact Tachibana, though the latter was rendered moot with Tachibana's death.
 * The Meteor Storm Switch (メテオストームスイッチ) has the ability to upgrade Meteor into Meteor Storm, accessing to the Meteor Storm Shaft weapon. It is created by Tachibana, but he feels Ryusei's not ready for it yet, due to his conceited nature. Ryusei later earns it when he goes to save the Kamen Rider Club instead of getting it when he was given the chance.

Super Galaxy King's Switch

 * The SOLU Switch is a special Astroswitch full of Cosmic Energy created from Nadeshiko at the cost of her physical existence. The SOLU Switch is used by Lem Kennagi to transform into Super Galaxy King. Utilized by the Galaxy King Driver and the Future Core Medals. As with the Gate Switch being a golden recolour of Fourze's Launcher switch, the SOLU Switch is a silver recolor of the Magic Hand Switch.

Legend Rider Switches
In the Kamen Rider Battle: Ganbaride arcade game, Kamen Rider Fourze is able to use special Astroswitches known as the Legend Rider Switches (レジェンドライダースイッチ) to access special Legend Rider Modules (レジェンドライダーモジュール) based on previous Kamen Riders. Each Legend Rider Switch has the "mask" of their respective Kamen Riders.

In the Movie War Mega Max, Kamen Riders Ichigo, Nigo, V3 and Riderman were turned into Switches and kept in a suitcase by a member of Foundation X. The Riders were able to return to their real forms when Fourze inserted the Switches into his Driver and performed a Limit Break.

Wizard
The Astroswitches, along with the other Rider Powers, were stolen from Fourze by Amadum in the world within the Magic Stone, who explained that they were already his due to the Riders' powers being from the same source as evil. However, the power was soon returned thanks to the appearance of Kamen Rider Gaim, with the return of the Astroswitches immediately transforming Fourze into Cosmic States.

Gaim
The Rocket Module is wielded by Kamen Rider Zangetsu when he uses the Fourze Lockseed to assume Fourze Arms.

 * The Astroswitches are similar to Kamen Rider W's Gaia Memories in various ways:
 * The Astroswitches/Rider Memories' dark counterpart are the Zodiarts Switches/Dopant Memories.
 * They can be either in solid colors or be translucent-colored.
 * The more powerful Switches and Memories are, the larger they get (i.e., the Fang Memory/NS MagPhone, the Trial Memory/Meteor Storm Switch, and the Xtreme Memory/Cosmic Switch).
 * Two of Fourze's Modules are similar to the arsenal of two previous Kamen Riders:
 * The Scissors Module's resting place (on the left arm) parallels that to Scissors' placement of his Scissor Visor.
 * The Claw Module is similar to OOO's Tora Claws.
 * Fourze requiring all 40 Astroswitches to access Cosmic States is similar to how Kamen Rider Blade used all 13 of the Spade Rouze Cards to access King Form.
 * Since this series, along with the previous series, is the 40th anniversary of the Kamen Rider Series, there are 40 Astroswitches made by OSTO. As such, each switch represents a year that a Kamen Rider series or movie has aired alongside a Super Sentai series and a series from 1971 to 2010.

 * The shapes on Fourze may seem like just simple shapes (not to mention highly coincidental to that of the Playstation), but the order of them relates to how they are drawn: a circle is one line in a loop, a cross is two crossed lines, a triangle is three connected lines, and a square is four connected lines. Thus, it makes perfect sense for the first four Astroswitches to be a Circle Switch, Cross Switch, Triangle Switch, and Square Switch, respectively
 * The name and rocket-theme of the Super-1 switch is possibly a slight reference to Kazuya Oki (Kamen Rider Super-1), who undertook surgery to become a man who can survive in outer space
 * The symbol of the Claw Switch looks similar to that to the symbol of SCRTC from Juken Sentai Gekiranger and the Order of the Claw from Gekirangers's Power Rangers counterpart, Jungle Fury.
 * The Nadeshiko Switch's symbol contains a lowercase n with the two lines forming rockets, which is possibly a reference to the fact that Nadeshiko created the means for Fourze to assume Rocket States.
 * Ironically, the Nadeshiko Switch is a Cross Switch, when Nadeshiko's Driver doesn't have the capacity to use either a Cross Switch or a Triangle Switch.
 * The Astroswitches are preceeded by the Lockseeds from Kamen Rider Gaim, which have similar properties:
 * Both have button properties.
 * Both have an evolutionary stage between the first and final states.
