Astroswitches

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

There are 40 known Astro Switches in total, each of which 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, Mojūru Beisumento). The shape of the colored portion of the Astro Switch also corresponds to the Module Basement.


 * Circle Module Basement (サーケルモジュールベイスメント, Sākuru Mojūru Beisumento): Right Arm. Circle Astro Switches in nature tend to be close-combat weapons, as well as having the capacity to change Fourze's States.
 * Cross Module Basement (クロスモジュールベイスメント, Kurosu Mojūru Beisumento): Right Leg. Cross Astro Switches 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, Toraianguru Mojūru Beisumento): Left Leg. Triangle Astro Switches 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, Sukuea Mojūru Beisumento): Left Arm. Square Astro Switches in nature tend to be battle-support items.

Switches

 * 1) Module 001.jpg Rocket Switch (ロケットスイッチ, Roketto Suitchi, Circle): The Rocket Switch arms Fourze with the Rocket Module (ロケットモジュール, Rokketto Mojūru) 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.
 * 2) Module 002.jpg Launcher Switch (ランチャースイッチ, Ranchā Suitchi, Cross): The Launcher Switch arms Fourze with the Launcher Module (ランチャーモジュール, Ranchā Mojūru) on his right leg, allowing him to attack enemies from a far distance.

The steel ball on the end of the chain is called the Blowing Star (ブローイングスター,Burōingu Sutā), weighing about 120 kg. The Rough Spikers (ラフスパイカー, Rafu Supaikā) on the Blowing Star are made from a newly discovered metal known as Astorium (アストリウム<, Asutoriumu). 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) Module 014.jpgSmoke Switch (スモークスイッチ, Sumōku Suitchi, Cross): The Smoke Switch arms Fourze with the Smoke Module (スモークモジュール, Sumōku Mojūru), 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.
