Heavy Duty Super-Colliding Super Button

The  1500 Megawatt Aperture Science Heavy Duty Super-Colliding Super Button is a game mechanic used throughout the Portal series. It is used within Test Chambers, and is activated when either a player or Weighted Storage Cube is placed upon it.

Uses
Buttons are present in virtually all test chambers and, when activated, trigger a variety of effects. Buttons can either control the flow of Excursion Funnels, open and close hatches, release Weighted Storage Cubes, or even open and close the gate leading to the exit. It's up to the player to figure out how and when to use the button, or buttons, in order to proceed.

Heavy Duty Super Button


The Heavy Duty Super Button is a receptacle that can be triggered by the weights of player characters, Weighted Storage Cubes, Edgeless Safety Cubes, and Frankenturrets. The button was introduced in Portal and remained prevalent in Portal 2.

An older prototype variant from the 50-70s era of the Super Buttons can be seen in the Portal 2 single-player chapters The Fall and The Reunion.

Weighted Storage Cube Receptacle


Weighted Storage Cube Receptacles, as obvious by its name, serves as a receptacle only for the Weighted Storage Cubes, even though it can also activate using Weighted Companion Cubes and Discouragement Redirection Cubes. This receptacle is only present in the co-op campaign of Portal 2, though it is available in the Puzzle Creator.

The Storage Cube must be placed securely inside the receptacle in order for test subjects to proceed. Although its appearance is similar to the Super Button, it cannot be activated by the weight of test subjects or any other objects being placed upon it.

Edgeless Safety Cube Receptacle


The Edgeless Safety Cube Receptacle is a receptacle for the Edgeless Safety Cube, introduced in Portal 2. The Cube must be placed securely inside the receptacle in order for the player to proceed.

Edgeless Safety Cubes and their receptacles only appear as testing elements in the game's cooperative campaign and the Perpetual Testing Initiative. However, an Edgeless Safety Cube can be seen among the "garbage" in Portal 2 Chapter 2 Test Chamber 6.

Contraption Cube Receptacle


The Contraption Cube Receptacle is exclusively featured in the educational version of Portal 2. Although it is designed for the Contraption Cube, the Receptacle will not recognize the Contraption Cube or activate any puzzle elements which are connected with it. Additionally, it appears entirely black in-game, when the model itself has different colors.

One-Touch Super Button
The One-Touch Super Button appears in Bridge Constructor Portal and is a blue variant of the normal Super Button that stays powered after being pressed at least once.

Trivia

 * In Portal Test Chamber 16, turrets can activate a button. This is the only occurrence of this.
 * The name GladOS introduces the button with - “Superconducting Super Button” - is a reference to the United States’ Superconducting Super Collider project, a failed attempt at creating a particle accelerator in Texas during the latter half of the 20th century.
