範囲第１項記載の絶縁抵抗測定用中性極開閉器。[Scope of Claim for Utility Model Registration] 1. A cylindrical rotating body having an inner diameter larger than the diameter of the shaft provided in the case is loosely fitted, and two contact points are provided that contact each other at two points on the outer periphery of the rotating body. , forming only the surface corresponding to the area between the two contacts on the outer periphery of the rotary body with a conductor, protruding an operating lever on the opposite surface side, and further applying a biasing force in the direction between both the contacts to cause the operating lever to start. A neutral pole switch for measuring insulation resistance, characterized in that the position of the conductor surface can be changed between a position where both contacts are electrically connected and a position where they are not connected by inversion movement. 2 The biasing force applied between the two contacts is due to a coiled spring that has one fulcrum supported on the case side and the other fulcrum on the rotating body side, and when the center of the shaft body is connected to the two contacts, the coiled spring is supported. The neutral pole switch for measuring insulation resistance according to claim 1, which is located closer to the center of the coiled spring than the straight line connecting both support points of the spring and moves to the opposite side when the two contacts are disconnected.
