PUSH BUTTON SWITCH ILLUMINATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an internal illumination apparatus of manipulation keys that can reduce the consuming power with lowering price as well as the number of luminous body being as a light source and that has no need to separately illuminate the manipulation keys even though a plural number of manipulation keys were arranged. SOLUTION: It comprises a plural number of manipulation keys, a plural number of switching elements for performing a switching operation by pressing the manipulation keys, which are arranged into a downward direction of the manipulation keys, a rigid body substrate for holding each of the switching elements into a downward direction of the manipulation keys, and a flexibility plate for passing light that is arranged between the manipulation key and the switching element and reflects an incident light from a light source arranged to its side toward the bottom of the manipulation key to be illuminated from the bottom. It inserts the flexibility plate for passing light by pressing the manipulation key and is achieved by the illumination apparatus of push button switch for pressing the switching element on the substrate.
