ドスイツチ。 A printed wiring board is formed by forming a thin film-like flexible wiring board with a group of electrodes placed at approximately symmetrical positions around the polygonal line, and wiring to connect these electrodes. In the case where the two electrodes are folded facing each other with a spacer in between and pasted together with the top sheet, the tip portion is bent by slightly shifting the fold line of the printed wiring board toward the back side. A keyboard switch characterized by being oriented downward.
