Switch

The switch tooltip tutorial as seen in the game.

The wire tooltip tutorial as seen in the game, showing the switch in-use on the wires layer.

The switch is a building used to control wires manually. Using LMB Interact on the building will toggle the state between off (grey) and on (green). While it is placed on the regular layer, the switch's only connection is a single output on the wires layer, which depending on the state will emit either false or true .
