Lever

The Lever is a 2x2 trigger for wiring activation. It is sold by the Mechanic. It can activate Statues, lights, etc. via right-clicking.

The Lever can be placed on any flat surface, the same as furniture, including on Wood Platforms. As of 1.2.3, it can also be placed on walls.

Despite its depiction as a switch with two positions, the Lever does not need to act as an on/off mechanism. When wired to Dart Traps, for example, right-clicking the Lever will always cause the Trap to shoot, the same as a Pressure Plate would, no matter which position the Lever happens to be in.

Trivia

 * The Inventory sprite shows it switched to the left side, although when you place it, it is switched to the right.
