ンブレンスイツチ。[Claims for Utility Model Registration] A plate with a key configured on its top surface, a conductive thin plate disposed opposite to the bottom surface of this plate, and a movable conductive thin plate disposed opposite to the bottom surface of this conductive thin plate. A first sheet on which contacts are formed and a second sheet on which fixed contacts are formed are stacked one on top of the other, and switches made of these movable contacts and fixed contacts are formed at positions corresponding to the keys, respectively. The switch corresponding to the pressed key is set to the on state by the pressing operation,
In the membrane switch, the membrane switch has a sheet-like switch part that automatically returns to the OFF state when the push-in operation is released, and a conductive ground plate that is disposed in opposition to the bottom surface of the sheet-like switch part. A membrane characterized in that conductive folded parts are formed on the side edges of a sheet-like switch part, and these folded parts are elastically pressed against the conductive thin plate and the ground plate, respectively. Switch.
