A relay is a switch. It is used for one of two reasons. (Also known as contactors, solenoids)
1. Current to be switched is high and it is desirable to keep the wiring as short as possible. So relay is mounted adjacent to the high current source and load where the high current contacts are wired in. The light current Control circuit wiring is then routed remotely to the controller (Switch). 2. About the same thing. The switching device is light weight, or in a crowded area and it is not desirable nor practical to have heavy current switching and wiring present. So a relay is used in some remote location to do the heavy work while being controlled by a light current control circuit.
