Claims

[Scope of utility model registration request]

A switch body has a passage for pressure fluid, a cylindrical case is hermetically connected to the body and has a pair of terminals, and a cylindrical case that slides inside the case and has an opening in the center and is located at a position offset from the center.
a disk-shaped receiver having a protruding part; a spring receiver that abuts against the receiver via the spring pressure in the case; one end of the center plate part is fixed to one terminal; A switch lever having a movable contact point at the tip of the central plate portion, separate from the tip of the center plate portion toward the fixed portion side, and each free end of which has a support piece that abuts the protrusion, and a contact portion between the protrusion of each of the support pieces. and a reversing plate whose periphery is supported by the receiver on the opposite side from the switch lever; A pressure switch comprising a diaphragm whose periphery is airtightly attached between the main body and the case so as to cover the reversing plate, and a rod provided in the opening of the receiver between the reversing plate and the switch lever.
