The KARCHER 6.997-549.0 electronic pressure switch is designed to automatically switch the pump on and off as needed on the pressure side. This innovative device features a dry-run protection mechanism to safeguard the pump from damage if no water flows through it from the suction side, such as when the water tank is empty. It is the ideal solution for converting a garden pump into an electronic booster pump. The electronic pressure switch is equipped with a G1 connection thread (33.3 mm).
