Abstract
A push-button switch has a plunger to be pressed so as to activate its main body supported by a base member. A cap serving as a pressing member is on an outer edge portion of the plunger. The outer periphery of the cap is surrounded by a frame part of a lens member made of a transparent resin material such that the light from a light source disposed near the center of the plunger is guided to the upper edge part of the frame part.
