Claims

[Claims for Utility Model Registration] 1. A switching valve whose valve switching operation is performed by displacement along the axial direction of a movable member, which is provided on the movable member and whose displacement is accompanied by the displacement of the movable member. a pair of second conductive parts that are provided on the outer periphery of the movable member and that are brought into conduction with each other and brought into a non-conduction state by contacting and separating due to displacement of the first conductive part; A switching valve comprising: 2. The switching valve according to claim 1, wherein the movable member is a main valve provided in a shaft hole. 3. The switching valve according to claim 1, wherein the movable member is a piston that operates a main valve provided in a shaft hole. 4. The switching valve according to claim 1, 2, or 3, wherein the first conductive portion is formed of a sealing member.
