れることを特徴とする圧力スイツチ。 A pressure switch comprising a pressure receiving piston airtightly fitted into a fitting hole formed in a housing, and a contact mechanism operated by displacement of the pressure receiving piston, wherein the base end portion is coaxially connected to the pressure receiving piston. a rod that is movable in the axial direction of the housing and has an annular protrusion formed on the outer periphery of the tip; a first spring that biases the rod toward the pressure receiving piston; a fixed cap having a first inward flange having a first central hole through which the tip is inserted; and a fixed cap that is axially movable in the housing and parallel to the first inward flange and through which the tip of the rod is inserted. a movable cap having a second inward flange with a second center hole; a second spring biasing the second inward flange toward the first inward flange; The contact mechanism includes a plurality of balls engaged between opposing sides and pressed radially inward toward the annular protrusion by the biasing force of the second spring, and the contact mechanism abuts the tip of the rod. A pressure switch characterized in that it is operated by.
