Switches are used to turn on and off powered floor squares and powered conveyors. There are four colors of switches: Red, Yellow, Green, and Blue. The Red switches control the Red Floors and Red Conveyors, and so forth.

Igor, the mummies, and the Helper Robots toggle switches by bumping into them. All the other movable objects are blocked by switches.

Beware of switches that have a white top, those are light switches and if bumped will turn off all the lights and the lab (computer screen) will go completely black. Can be annoying if it happens by accident, but can be very helpful when trying to sneak by scurries. Lights will stay off until a light switch is bumped again.
