Claims (1)
光板に光を入射する光源と、導光板の表面に被着
されたシート状のメンブレンスイツチとによつて
構成された内照式メンブレンスイツチにおいて、
上記導光板は背面の要所に突起を有し、この突起
の中央に上記導光板の板面に対して鉛直方向の軸
芯を持つ光源挿入用穴が形成され、外周には導光
板に向つて漸次太くなる傾斜面が形成されている
ことを特徴とする内照式メンブレンスイツチ。 An internally illuminated membrane switch consisting of a light guide plate made of a transparent plate, a light source that enters light into the light guide plate, and a sheet-like membrane switch adhered to the surface of the light guide plate. In,
The light guide plate has protrusions at key points on the back surface, and a light source insertion hole is formed in the center of the protrusion, the axis of which is perpendicular to the plate surface of the light guide plate, and the outer periphery is oriented toward the light guide plate. An internally illuminated membrane switch characterized by a sloped surface that gradually becomes thicker.
