Automatic pressure switch 0.4bar Uni Quick 12mm (JG) Automatic pressure switch, check valve for water pumps to function as pressure pumps.
Used in combination with water pumps acting as pressure pumps. After reaching the pressure of 0.4 Bar in the installation, the switch will stop the pump operation. If you connect city water directly to the installation (bypassing the tank) using e.g. a 'Colorado' pressure reducer, the switch will work and when you turn on the tap, the submersible pump will not turn on ( water flows from the external connection). After disconnecting the water from the outside, the pressure in the system will drop and unscrewing the tap will activate the submersible pump in the tank.
You cannot use an automatic switch, like an 'on' switch for taps without microswitches, using a submersible pump.
When at rest, the pins are shorted! After reaching 0.4 bar, the pins are open!
For connection to the Uni Quick 12 mm system.
