Claims

[Claims for Utility Model Registration] 1. A pressure-responsive shaft consisting of a case of the pressure switch body and a base for closing the opening of the case, and within the case, the pressure-responsive shaft is slidably supported by the base. , a fixed contact and a movable contact that open and close with the sliding movement of this pressure-responsive shaft, an elastic plate that supports this movable contact near the fixed contact, and an elastic plate that engages with this elastic plate and extends in the axial direction of the pressure-responsive shaft. A sliding member extending for opening and closing both of the contacts is provided at the end of the sliding member on the base side, and a sliding/moving member operating protrusion that protrudes outside the case via the base. A recess for storing the protrusion and a hole for protruding the protrusion that communicates with the recess are provided on the inner surface of the case and the outer circumferential surface outside the case, respectively, and the hole is provided with a recess for storing the protrusion and a hole for protruding the protrusion that communicates with the recess. A pressure switch whose width is approximately equal to or larger than the sliding distance of a sliding member. 2. When the base presses the sliding member operation protrusion against the peripheral wall near the hole for projecting the protrusion, the sliding member slides, and the movable contact is separated from the fixed contact, the protrusion is removed. 2. A pressure switch according to claim 1, wherein a fixing piece is slidably provided to fix the sliding member in the above-mentioned state when the sliding member is slid to the elastic return side of the portion.
