Relay
A relay is an electrically-controlled switch that allows a low current circuit to control a high current circuit. It is used to control electrical components in a vehicle, such as the fuel pump, starter motor, and air conditioning compressor. Relays help manage electrical loads and protect sensitive electronics.
