Abstract
The utility model relates to a waterproof high-pressure switch which comprises a housing, where a water inlet channel, a water outlet channel, a hydraulic pressure chamber are arranged. A diaphragm for controlling the on/off of the water inlet channel and the water outlet channel is arranged in the hydraulic pressure chamber. A microswitch is arranged in the housing, and the diaphragm cooperates with the microswitch. Insertion pins are arranged in the housing, and the insertion sheet pin is connected with the microswitch. A through hole allowing the insertion sheet to penetrate through is arranged in the housing. The waterproof high-pressure switch is characterized in that a sealing member is arranged between the insertion sheet pin and the housing. In such a structure, the waterproof high-pressure switch prevents water and impurities from entering into the housing to ensure the working performance stability of the high-pressure switch.
