This switch can be used in any standard 12V application. It has a circular design, and can be clipped into place into a 3/4 inch hole. It is intended to interrupt positive signal, and the LED can then be activated when the switch is turned on by connecting the switch to ground.
The connectors on the back are standard male spades, and standard insulated female spade connectors, such as those found on our store, are recommended for easy connection. Details:
