ABSTRACT:
An illuminated pushbutton switch cover member has a key seat and a resin key top. An indicator portion provided in the resin key top is illuminated with light from an internal light source provided below the key seat, and the light is emitted from the inside to the outside of the cover member through the indicator portion. The cover member is constructed by joining the resin key top to the key seat. The key seat is formed of a thermoplastic elastomer that prevents leakage of light, and an opening for passage of light is formed in the key seat to expose the bottom side of the resin key top to the internal light source. Thus, light from the internal light source can reach the bottom side of the resin key top directly without being attenuated. The indicator portion of the resin key top can therefore be illuminated with high luminance.
