とをスペーサの透孔を介して接離自在に対向配置
してなるスイツチ部と、該スイツチ部の前面を覆
い所定位置に照光部を有する表示シートとを備え
、上記光源から出射された光が上記スイツチ部を
介して上記表示シートの照光部に照射される照光
式メンブレンスイツチにおいて、上記スイツチ部
のスペーサのうち上記表示シートの照光部と対応
する位置に光を透過せしめる光透過部を設けると
ともに、該スペーサの該光透過部および上記透孔
を除く部分に光反射性を有する材料を含有せしめ
たことを特徴とする照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 light emitted from the switch part is irradiated onto the light-emitting part of the display sheet through the switch part, the light is transmitted through a spacer of the switch part at a position corresponding to the light-emitting part of the display sheet. 1. An illuminated membrane switch characterized in that a light transmitting portion is provided, and a portion of the spacer other than the light transmitting portion and the through hole contains a material having light reflectivity.
