光式メンブレンスイツチ。 A light guide plate having a light transmittance inside and a light reflectivity at least on the bottom side, a light source for illumination built into the light guide plate, and a sheet placed on the light guide plate and formed into a light transmittance sheet. a switch section in which an upper electrode and a lower electrode are disposed facing each other so as to be able to move toward and away from each other through a through hole in a spacer; and a display sheet that covers the front surface of the switch section and has a lighting section at a predetermined position, In the light-emitting membrane switch in which the light emitted from the light guide plate is irradiated to the light-emitting part of the display sheet through the switch part, a mounting hole is provided at a predetermined position of the light guide plate, and the light exits through the mounting hole and is guided to the outside. An illuminated membrane characterized in that an LED lead is embedded in the light guide plate, a chip-shaped LED is arranged as the light source in the mounting hole, and the chip-shaped LED is connected to the LED lead. Switch.
