Switch

The Switch is an activation mechanism sold by the Mechanic. It can also be found in the Dungeon connected to Chain Lanterns, and can be harvested with the Hammer.

The Switch can be placed on top or on the sides of blocks, or on the sides of Wooden Beams. As of 1.2.3, switches can be placed on walls. It is activated by right-clicking on it.

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