成を有することを特徴とする圧力スイツチ。[Claims for Utility Model Registration] A housing having a cylinder hole, a piston that is slidably disposed within the cylinder hole and receives operating pressure in the axial direction, and a piston that is disposed between the housing and the piston and that A pressure switch having a spring member that biases the piston in a direction against the operating pressure, and a contact mechanism having a movable contact member provided between the housing and the piston and driven by the piston, The movable contact member is a plate-like member made of an elastic material having an abutting portion at one end, the other end being fixed to the housing, and an intermediate portion having an arc-shaped cross section and being pressed by the piston. A pressure switch characterized in that, when pressed, the contact portion is bent to a side fixed to the housing from the intermediate portion, thereby causing a large displacement of the corresponding contact portion.
