ム等の受圧素子と、この受圧素子に接して上記変
形に追従移動するプランジヤと、このプランジヤ
の移動によりオン・オフするスイツチ部とを備え
た圧力センサであつて、 上記受圧素子の反動作側において、該受圧素子
を保護する保護キヤツプを設け、 この保護キヤツプの受圧素子対向面にノーマル
状態で受圧素子と非接触となる対負圧用の凸部を
一体形成した 圧力センサ。[Claims for Utility Model Registration] A pressure-receiving element such as a diaphragm that deforms in response to changes in fluid pressure, a plunger that contacts the pressure-receiving element and moves to follow the deformation, and a switch that is turned on and off by the movement of the plunger. A pressure sensor is provided with a protective cap for protecting the pressure receiving element on the non-operating side of the pressure receiving element, and a surface of the protective cap facing the pressure receiving element is not in contact with the pressure receiving element in a normal state. A pressure sensor with an integrally formed protrusion for negative pressure.
