請求項(1)記載の圧力スイツチ。[Claims for Utility Model Registration] (1) A fixed contact fixed to a casing, a movable contact slidably mounted in the casing via a movable contact holder, and the movable contact a pressure setting spring that urges the movable contact holder to keep it in a non-contact state with the fixed contact; and a piston that is slidably attached to a body fixed to the casing and has one end abutting the movable contact holder. and a diaphragm attached to the body surrounding the other end of the piston, the diaphragm receiving pressure from a hydraulic circuit or the like to bias the piston against the biasing force of the pressure setting spring. In the pressure switch in which the fixed contact and the movable contact are brought into contact with each other, the movable contact is pressed against the movable contact holder by a spring, and the movable contact holder is pressed by a guide member fixed to the body. A pressure switch that can be slid in the axial direction. (2) The pressure switch according to claim (1), wherein the movable contact is plate-shaped, and the movable contact and the fixed contact are in surface contact at two points, and the contact surface is perpendicular to the moving direction of the plate-shaped movable contact. .
