Pedestal Button

Pedestal Buttons are a game mechanic used within the Portal series. They can be found very frequently throughout Test Chambers and are primarily used to allow the player to trigger or toggle a particular function. They can be activated with the "Use" key (default: ).

Uses
Pedestal Buttons are used for multiple purposes to initiate a particular action. More common uses include the dropping of a Cube, activating a Gel pipeline and opening a door. They can also be timer-based, where the action, for example -- extending a platform, is only activated for a specific length of time.

Trivia

 * The bonus chambers of Portal: Still Alive feature an alternate version, which has red lines on the sides (instead of blue) and has a red cube with a skull in the center on the actual button part. This variation is only used for buttons which respawn cubes, as this feature is never present in Portal's campaign.
