Square D™ FSG2J21BP Water Pump Low Pressure Cut Off Switch 30-50 PSI

Water Pumps are used to bring up the water from the well and to pressurize the water pipes in the home. Water is pumped into a storage tank to compress an air bladder that exerts pressure on the water in the home. When the desired pressure is reached, the pump must be stopped and the pressure switch opens a set of electrical contacts to stop the pump. When the water pressure falls to the lowest desired pressure the switches close to start the pump and recharge the system pressure. The most common water pump pressure settings are 20 to 40 PSI, 30 to 50 PSI, or 40 to 60 PSI. The lower number is the cut-in pressure and the higher number is the cut-out pressure.
