Abstract
A pushbutton switch mechanism has board 28 incorporating an electronic circuit thereon, metal sheet contact 26 disposed on board 28, a light-transmissive pushbutton disposed in an opening defined in a casing of the electronic device for being pressed from outside, the light-transmissive pushbutton having outer key top 22 and presser 25 formed with rubber sheet 24 for contacting metal sheet contact 26, and light-emitting elements 27 disposed on board 28 around presser 25 for applying light to a side surface of the presser 25. Presser 25 has a conical shape having an upper surface as a bottom surface substantially aligned with a lower surface of key top 22 and a vertex for contacting metal sheet contact 26. Light emitted from light-emitting elements 27 is applied to the entire side surface of presser 25.
