Claims (1)

[Claims for Utility Model Registration] (1) An operating shaft that is operated to reciprocate in the axial direction, a movable plate having movable contacts at both ends and provided perpendicular to the operating shaft, and the movable contact. fixed contacts disposed on both sides of the operating shaft so as to face each other; and two sets of inverter blocks provided between the operating shaft and the movable plate, the inverter blocks being expandable and retractable. It consists of two pieces fitted together and a spring that always urges them apart, one of the two pieces being engaged with the operating shaft and the other being engaged with the movable plate. In a switch in which a movable plate is moved in the axial direction of the operating shaft by reciprocating motion of the operating shaft to open and close between the movable contact and the fixed contact, one of the two pieces The fitting part has a fitting hole at the end, and a hollow part that extends from the fitting hole at the back of the fitting hole, and the fitting part of the other piece has a fitting hole at the end. The locking piece is formed to fit into the hole in a predetermined direction and protrudes outward to be larger than the size of the fitting hole due to its elasticity, so that it cannot be pulled out from the fitting hole. A switch characterized by being stopped. (2) The two pieces are each formed into a polygonal shape in which the fitting portion and the fitting hole fit into each other without any gaps and in multiple fitting directions, and each piece engages with the actuating shaft and the movable plate. A request for registration of a utility model in which an engaging groove is formed in an engaging part to be mated, and at least one of the engaging parts has a plurality of engaging grooves, so that it can accommodate a plurality of mating directions. The switch described in item 1 of the range.
