The switches are the centerpiece of the room's memory game, in which players must flip the switches in the color order corresponding to the flashing "Failure" sign, which must be noticed at the beginning of the game.
There are at least two options to make them self resetting:
- Two magnetic sensors, one at the top and one at the bottom, are activated alternately each time a group goes into the room. This means that the switches merely have to be flipped to the opposite side the next round.
- The top magnetic sensor is also an electromagnet that is inactivated briefly after a group goes through the room to drop the switch into the lower initial position.
