特徴とする圧力スイッチ。A movable contact attached to the inner surface of the diaphragm is provided in an airtight switch chamber of an insulator separated by a diaphragm that applies positive or negative pressure, and a fixed contact corresponding to the movable contact is provided in the airtight switch chamber, Two or more stages of ring grooves are provided on the outer periphery of the insulator, a waterproof cap is tightly fitted and fixed to the outer periphery of the insulator including these ring grooves, and the airtight switch chamber has an opening in the uppermost ring groove for communication with the atmosphere. A hole is provided, and fine communication grooves are provided at several locations between the outer periphery of the partition wall of each annular groove and the inner surface of the waterproof cap to sequentially communicate with the lower annular groove. A pressure switch characterized by forming a bent air passage leading to the opening of the communication hole, and further providing a small gap between the hem of the waterproof cap and the outer periphery of the insulator leading to the bent air passage.
