Our Store Features : 　 1/4″ High Pressure Switch. Quick connected for 1/4″ tube, pipe. The high pressure switch is normally closed if the pressure is high enough, or it is opened while the pump is switched off. Suitable for pump, water filter, aquarium, etc. The high pressure switch is designed to cut the pump off when a set pressure is reached and are generally used in either a pressure tank equipped system or an open tank system using a float valve. This would be located as close as possible to the pressure tank or the float valve. In this situation, it keeps the system maximum pressure from being reached and keeps the pump from running continuously. When water pressure tank is full of water, High Pressure Switch will automatic power down system and will be kicked off when insufficient pressure/water occurred (pressure down 0.06Mpa). General pressure setting for High Pressure Switches is 0.25Mpa±0.03Mpa (about 40Psi).
