A classic example is the system used to start a car when someone turns an ignition key the ignition does not interact directly with the car battery instead it activates a relay which passes the signal on so that the car can start.

Relays are used where it is necessary to control a circuit by an independent low power signal. The factory wiring in modern cars is light gauge and is not designed for additional loads. They are found in all types of vehicles. Every circuit added to a modern car should be run through an automotive relay.

If so the trigger circuit of the relay electrical system is working if not continue to next step. A relay is an electrically operated switch it consists of a set of input terminals for a single or multiple control signals and a set of operating contact terminals the switch may have any number of contacts in multiple contact forms such as make contacts break contacts or combinations thereof.
