The switches themselves are yellow and are placed on a grey block.
Switches can be pressed by the owl and can either turn a laser to the direction perpendicular to where the laser originally was or remove the laser, depending on what their set behaviour is.
Occasionally, there will be several switches featured in a level that the player must figure out which one will turn off the correct laser. A movable block, if available, may also be used when the switches will not turn the lasers off in the way the player would like it to go in.
If a player turns a switch, then presses pause, then presses resume, the switch would have reverted back to its original side where it laid untouched.
