特徴とする圧力スイツチ。 A housing with a fitting hole formed along the center;
A switch case coaxially fixed to one end of the housing, a switch mechanism provided inside the switch case, and a switch mechanism that is fitted into the fitting hole in a fluid-tight manner and has one end in contact with a movable member of the switch mechanism. In a pressure switch consisting of a pressure receiving piston that operates a switch mechanism, a small diameter portion is formed at a tip end of the pressure receiving piston on the side of the switch case, and a large diameter hole is formed in a portion of the housing corresponding to the small diameter portion and continues to the fitting hole. The entire outer periphery of a thin sheet member made of a flexible elastic material is liquid-tightly fixed to the housing near the periphery of the large diameter hole, so that the internal space of the switch case is defined between the small diameter part and the large diameter hole. A pressure switch characterized by being airtightly partitioned from a space formed in the air.
