    Assuming the general description of a relay here, it's an electrical component that uses an electrical signal to switch on another electric circuit. For instance, your key-start in a car switches on a relay of sorts. A lower electricity level activates an electromagnet in the relay. The electromagnet pulls two contacts together, switching on a higher electricity circuit. This one turns on the starter and starts the engine.
