Abstract
A switch according to the present invention has a plurality of protruding parts and a plurality of support sections both of which are formed on a surface of a thin metal sheet by press molding. The switch includes a plurality of switch sections formed by elastic deformable conductors arranged so as to have a convex surface opposed to the protruding parts, a wiring sheet covering the conductors, and switch buttons. At least one support portion is provided around the protruding parts and a gap area is left between the protruding parts and a switch sheet. In this gap area, each conductor is accommodated at the same position as the protruding parts. The support sections are disposed in a dotted-form to accomplish improvement of a feeling of click that is one of the performances on which the user places much value. In addition, a casing, the protruding parts, and the support portions are press-molded of a thin metal sheet, thereby obtaining the effect of reducing wall thickness and increasing the rigidity.
