化したことを特徴とする圧力スイツチ。[Claims for Utility Model Registration] An actuating rod is provided that responds to fluid pressure transmitted through a diaphragm, and an electric switch is provided that is turned on and off by movement of the actuating rod. A permanent magnet is fixed to the housing by penetrating the outer periphery of the actuating rod, and the actuating rod is returned to its original position.
When in the operating position, a magnetic member that is attracted by a permanent magnet to increase or decrease the biasing force of the spring is locked to the operating rod, and the on/off operating width of the electric switch is set to speed up the switching operation. A pressure switch that is characterized by being reliable .

ツドを設け、この作動ロツドの移動によりオン・
オフする電気スイツチを設ける一方、前記油圧に
対向して作動ロツドを押圧するスプリングを設け

を特徴とする圧力スイツチ。 An actuation rod is provided that responds to the hydraulic pressure transmitted through the diaphragm, and the movement of the actuation rod turns on and off.
An electric switch is provided to turn it off, while a spring is provided which presses the actuating rod against said hydraulic pressure, and which passes through the outer circumference of the actuating rod and secures a permanent magnet to the housing so that when the actuating rod is in the actuated position, a permanent magnet is provided. A pressure switch characterized in that a magnetic member that is attracted to a magnet and reduces the biasing force of a spring is secured to an actuating rod.
