A Power Switch is a Utility that is used to control the flow of electricity between a section of Electrical Cable and a Power Station, Capacitor, or another section of Electrical Cable. A Power Switch can be in one of two states: On or Off. When On, it functions as an Electrical Cable, allowing electricity to flow through. When Off, it prevents electricity from flowing through.
They are generally used to cut the power down of an area where something dangerous could occur, I.E. the kitchen: fire can be prevented if power is down during a riot.
There is currently a bug relating to connecting a power switch to a Logic Circuit - the Power Switch will always send an On signal regardless of state. As a workaround, connect the Power Switch first to a Logic Bridge, and then to the Logic Circuit.
The Power Switch can be placed in any location that is not already occupied by another object or wall.
