特徴とする圧力スイツチ。 A switch housing that can be attached to a mating member, a fixed terminal that is fixed to a fixing hole at one end of the switch housing via an insulator, and a fixed terminal that is normally attached to the switch housing in a non-contact state by a spring. A pressure switch comprising a movable contact to be held, and a pressure receiving pin that is provided integrally with the movable contact and receives pressure between pressure circuits of a member to which the switch is attached,
O for sealing between the inner peripheral wall of the fixing hole and the fixed terminal
1. A pressure switch comprising a ring, and a convex portion formed on an inner circumferential wall of the fixing hole to prevent axial movement of the O-ring.
