It comprises an outer frame (3) having a parts storing chamber (3a), a circuit substrate (4) stored in the parts storing chamber (3a) and having mounted thereon a light emitting diode (10) and a pair of fixed contacts (11a, 11b), a light-permeable depressing member (5)stored on the front surface of the parts storing chamber (3a), movable in the direction of thickness of the outer frame (3) and urged by the spring force of a compression spring (7) toward the front surface, and a color plate (6) fixed to the back surface of the depressing member (5) and having a movable contact means for diffusing the light from the light emitting diode (10) and shooting uniform light toward the depressing member (5) so that it passes between the pair of fixed contacts (11a, 11b).
