The universal high / low pressure switch is intended for use in reverse osmosis water treatment systems and booster pump controls. It is installed after the pump, before the tank. Turns the pump off when the required tank pressure (factory set to 40+5 PSI) is reached and switches on when the pressure drops (factory set to 20+5 PSI). Prevents damage to the pump from dry operation. ON / OFF parameters can be set, from 20 to 40 PSI.
Note: you must have a special instrument and pressure measuring device for adjustment!
