Claims

[Claims for Utility Model Registration] 1. In the structure of a membrane switch that performs electrical switching by applying conductive printing to a plastic film, a conductive pattern including fixed electrodes that serve as the positive and negative terminals of the switch is printed on the first plastic film. a contact film, and conductive printing is applied to the back surface of an operating part, which is formed by forming a part of a second plastic film into a flexible dome shape, in contact with the fixed electrode to become a movable electrode, and on the contact film. A structure of a membrane switch characterized by comprising an operation film superimposed on a membrane switch. 2. The membrane switch structure according to claim 1, wherein the operation film and the contact film are fixed with double-sided adhesive tape.
