Claims

[Scope of utility model registration request]

A push button protruding from the top surface is connected to form a plate-shaped operating shaft that is spring-biased upward, and a plate-shaped, elastic, conductive operating spring that has a movable contact that faces a fixed contact at its tip. , the tip of an elastic locking piece integrally extended inward from the inner edge of the actuation spring formed in a substantially square shape is cut on both sides of the actuation shaft over the entire width direction of the actuation shaft. In a switch that is engaged in a locking groove provided in the switch and is pressed downwardly on a ζ push button, an operating spring is reversely driven via an operating shaft to open and close a movable contact and a fixed contact. A first locking groove is formed approximately at the center by closing both sides of the locking groove on the side surface, and a second locking groove is formed approximately at the center by closing the locking groove at the other side surface, and second locking grooves are formed at each side of the closed portion by closing the approximately central portion of the locking groove on the other side surface. A locking groove is formed, and a locking tongue piece that locks with the first locking groove is formed approximately at the center of the tip of one of the locking pieces of the actuation spring, and a locking tongue piece that locks with the first locking groove is formed at the approximate center of the tip of one of the locking pieces of the actuation spring. A structure of a switch characterized in that a locking protrusion is formed on both sides of the tip of the piece to lock with a second locking groove, respectively.
