項記載のメンブレンスイツチ。[Claims for Utility Model Registration] 1. A pair of insulating resin sheets 11A, 11B laminated at intervals, and lower layer electrodes 13 formed on mutually opposing surfaces of the sheets, respectively.
13, and a plurality of upper layer electrodes 20 formed on a surface of one of the pair of sheets opposite to the surface on which the lower layer electrode is formed, at intervals from each other in the surface direction.
A, 20B, and a click plate 15A made of an elastically deformable and conductive material and formed into a curved plate shape so that the end portion contacts the sheet surface and the middle portion separates from the sheet surface. The membrane switch is characterized in that the click plate is disposed on the sheet surface at a position where an end portion is in contact with one of the upper layer electrodes and a middle portion is away from the other upper layer electrode. 2. Utility model registration claim 1, characterized in that a protrusion 22 protruding toward the upper layer electrode is provided near the apex of the curved portion of the click plate.
Membrane switch described in section.
