を特徴とする圧力スイツチ。 A polymer consisting of a ferrite core incorporating an amorphous diaphragm and a pick-up coil can be slid freely along the inner wall of the case via an elastic sealing member into the chamber inside the case where pressure is introduced from the pressure introduction path. In this case, the polymer is received by a plate attached to the case side so as to close the open end of the case, and a dish-shaped cup seal is used as the sealing member, and the lip part of the cup seal is placed on the inner wall side of the case. A pressure switch characterized by being provided with a pressing spring member.
