PROBLEM TO BE SOLVED: To provide a press-button switch for which the shape of a handle mark will not be deformed due to aging, abrasion or the like. SOLUTION: A handle mark fitting hole 11b, where a bottom surface, recessed round is closed, is formed at one end part of a square front surface of a handle body 11a. A hooking hole 11c is formed at each 90 deg. on the circumference, at a part of the handle mark 11b where the bottom surface crosses an inside wall surface. A hooking tab 10e is protruded at each 90 deg. in circumference, at a part of a handle mark 10 molded into a disc which serves as a measure of the function of the operation handle 11, where its bottom surface crosses an outer wall surface. By hooking the hooking tabs 10e with the hooking holes 10c, the handle mark 10 is fitted to the handle mark fitting hole 11, the shape of the handle mark 10 will not be deformed through aging, abrasion or the like.
