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.

The circuit that powers the electromagnet s coil is completely separate from the circuit that is switched on or off by the relay s switch so it s possible to use a relay whose coil requires just a few volts to turn a line voltage circuit on or off. An electrical relay is a switch that is under the control of another circuit.

Relays line electric company specializes in hard to find general purpose relays that were manufactured by potter brumfield magnecraft deltrol struther dunn and others over the years. Plug in relays are used when a machine must control a circuit with a lower power signal or when several circuits must be controlled with one signal. 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. Relays are used where it is necessary to control a circuit by an independent low power signal.

A relay is an electromechanical device that uses an electromagnet to open or close a switch.
