PROBLEM TO BE SOLVED: To extend the area of a lighting part to improve the visual confirmability in switch operation and designing property, and reduce the number of light emitting elements by providing a conical light reflecting frame around a light emitting element. SOLUTION: The light from a light emitting element 1 is reflected and diffused by a conical light reflecting frame 2 provided around the light emitting element 1. Since the light is further bent in the inclined part on the inside of a push-button switch operating part 3, the display character 4 of the push button switch and the circumferential part 5 of an operating part 3 are lighted. Therefore, since the area of the lighting part is extended, and the number of light emitting elements used is minimized, the color convergence and dispersion in luminance by individual dispersion of light emitting elements are prevented, and the assembling property of the switch is also improved. The light reflecting frame 2 is desirably used also as the radiating plate of the light emitting element 1. The inside of the operating part 3 may be conically formed. |
