Abstract
A push switch includes an operating body, a case, a return spring, and a light source. The operating body is controlled by push operation, includes a through-hole in the center and a display portion at the upper edge of the through-hole, and supports a movable contact unit. The case has the insert hole on a bottom surface opposing the through-hole and fixed contact units on an inner surface of the sidewall. The movable contact unit comes into contact with fixed contact units. The return spring is interposed between the case and the operating body and returns the position of the operating body in the reverse direction of the push operation. The light source stored in the insert hole and the through-hole. The through-hole is formed linearly in the direction the operating body is moved during the push operation so that the light source does not interfere with the operating body.
