を特徴とするギヤ変速位置検出用スイッチ。A conductive metal case electrically connected to the ground side, a board mounted to cover the opening of the case, and a bearing that is placed concentrically with the board to rotate integrally with the gear shift drum of the gear transmission. a rotating shaft made of an elastic conductive metal, fixed contacts arranged on the substrate on a concentric locus with the rotating shaft and spaced apart in the circumferential direction in a number corresponding to the number of gear speeds; a first movable contact, which has a contact portion that alternatively contacts the fixed contact by rotating integrally with the first movable contact, and the first movable contact is biased toward the fixed contact by its own elasticity; It has a contact part that is electrically connected to the first movable contact, rotates integrally with the rotating shaft, and is always in contact with the inner surface of the case, and the contact part is moved by its own elasticity to the inner surface of the case. In the gear shift position detection switch, the second movable contact is energized by the fixed contact, and the second movable contact is connected to a portion of the case that the contact portion of the second movable contact comes into contact with. A recess is provided in which the contact part of the movable contact removably engages, and the contact part of the second movable contact engages with the recess, so that when the first movable contact and the fixed contact come into contact, A gear shift position detection switch characterized in that the center positions are configured so that they coincide with each other.
