A pump relay switch is often seen in well applications to pump water from the well to your home or building. A pump relay switch is used with higher horsepower submersible pumps and signals to the pump when to turn on and off.
Pump relay switches can be thought of as buffers between the pump pressure control switch and a heavy-duty water pump. For lighter water pumps, the on/ off pump action is controlled by the pressure control switch directly. However, the problem arises when the water pump has too high a voltage/amperage combination. Large horsepower water pumps can easily draw more than 15A—enough amperage that would cause the pressure control switch to be burned up rapidly.
In case of emergencies, many water pump relay switches come integrated with a special electrical shut-off feature. This feature is activated when the pump relay cover is removed. Inside, you’ll see a pull-out switch that cuts electrical power to the pump. This is important for two reasons:
Pump relay witches play vitally important roles in the efficiency and success of your automated well water transport system. Pump relay switches are designed to work alongside heavy-duty, high horsepower submersible pumps that would otherwise burn out pump pressure control switches.
