You will receive a pressure switch for domestic water pumps.

You will receive a mechanical pressure switch as used in domestic waterworks and garden pumps. AC pressure switch for water pumps, preferably for domestic waterworks with pressure tank or garden pumps.

Both the switch-on pressure and the switch-off pressure are infinitely adjustable. It is a single-phase switch that switches both the phase and the neutral conductor simultaneously. The switch automatically switches a pump via the applied water pressure. The switch-on pressure and switch-off pressure are infinitely adjustable. If the pressure in the water circuit falls below the switch-on pressure, the pump is switched on; when the switch-off pressure is reached, it is switched off again (pressure monitor).

Setting the pressure switch:

1. loosen the differential pressure nut (2).
2. set the switch-on pressure (1).
3. screw in the differential pressure nut (2) until the switch-off pressure is reached.

If your pump has an output of more than 1.1 kW, you should connect a commercially available power contactor or an appropriate power relay upstream. 380/400 V three-phase pumps can also be controlled with a 380 V power contactor.
