Aameria RO High Pressure Switch HPS Switch / Valve (1/4" Qc x 1/4" Qc) for RO Water Purifier Automatic Control Valves

HPS (High Pressure Switches), are basically a simple electro- mechanical device functioning on the following basic principle: When a any change occurs in water pressure on High pressure side of an elastic diaphragm, it shifts transmitting a force to a pre calibrated snap switch. So when Diaphragm motion is opposed by a calibrated spring inbuilt in the micro switch that determines the range of the switch.The HP switch is located at the supply water side of Booster Pump and it will turn OFF the pump in case of water is stop coming from main supply or of the pressure is very High for functioning of the RO.
