光式キーが記載されている。2. Description of the Related Art Heretofore, illuminated pushbutton switches composed of a translucent resin key top and a translucent elastic keypad have been widely used as pushbutton switches for portable communication devices such as cellular phones and car phones. . Above all, an illuminated push button switch in which a light-transmitting resin key top having a display portion on the back surface and a light-transmitting elastic keypad made of a rubber-like elastic body are bonded with a light-transmitting adhesive is preferred. In Japanese Patent Publication No. 2627692, a display portion that illuminates only a character portion is printed on the back surface of a key top formed of a translucent hard resin,
An illuminated key bonded with a light-transmitting silicone rubber and a light-transmitting adhesive is described.
