What is a pump relay switch used for?

A pump relay switch is used to switch on or off a fuel, water or heat pump in a home. This type of switch controls the flow of electricity from the main power source to the motor of the pump.

Apart from ensuring continuity of electricity flow, a pump relay switch regulates the safety of this flow between the circuit and the pump by controlling large voltages. This control mechanism protects the circuit from damages caused due to overload or reverse currents. Apart from home use, pump relay switches are used extensively in the automobile sector as well as for sprinklers and agricultural irrigation.
