Abstract
Outer ends of link members supported to a case and having their inner ends coupled to each other are coupled to a slider. A membrane sheet and a pusher are disposed one after the other on the slider, and a knob having molded therewith a surface sheet is fixed to the slider. On a bottom plate are mounted a tactile push-button switch and a light source. No matter which press area is depressed, the slider is uniformly translated by the link mechanism to actuate the push-button switch. The link mechanism, the slider, the membrane sheet except conductor portions, and the pusher are formed of a light transmitting material.
