Illuminated button switch

摘要

An illumination type push button switch includes EL element 20 mounted to a bottom surface of board 17 below switch contact 2. Board 17 has through-holes 17A and 17B near the contact. EL element 20, which is capable of lighting plural push buttons simultaneously by surface-light emission, emits light via through-holes 17A and 17B of board 17 to light push buttons 11 and 12. The illumination type push button switch thus lighting the push buttons clearly includes a small number of components and is inexpensive.
