Claims

[Claims for Utility Model Registration] A housing having a cylinder hole and a contact chamber communicating with the cylinder hole, a piston slidably disposed in the cylinder hole and receiving operating pressure in the axial direction, and a piston in the contact chamber. a contact mechanism disposed between the piston and the contact mechanism that opens and closes the circuit by the pressure of the piston; and a contact mechanism disposed between the piston and the contact mechanism that transmits the pressure of the piston to the contact mechanism and also connects the cylinder hole and the contact chamber with fluid. a pressure switch having a seal member that tightly separates the piston and the contact mechanism, the seal member separating the piston and the contact mechanism, sealing the contact mechanism and having a through hole; a shaft inserted into the hole; a rod stopper provided on one end surface of the shaft and having an abutment portion that abuts the piston and closely contacts one surface of the seal;
A pressure switch comprising: a seal clamping part that closely contacts the other surface of the seal, is fitted onto the shaft part, and clamps the seal together with the rod stopper.
