Abstract
A membrane switch device is described which is composed of two membrane switch arrays which are in parallel closely spaced relationship. A first or original array of membrane switches is provided on a sheet of flexible insulating film which has been folded about a medial fold line so that the switch electrodes on the two opposed surfaces are in alignment. The electrodes have conductors extending therefrom which extend onto a tail. A second array is provided on an extension of the sheet of insulating film and this extension also is folded about its own medial fold line. Additional electrodes and conductors are provided on the extension. A slit is formed between the original section of film and the additional section and the tail is inserted through this slit when the first array is produced by folding the first or original section of film. After the second section or extension of the film is folded to produce the second array of switches, the entire second switch array is folded as a unit towards the first array so that both switch arrays are adjacent to each other and are in parallel planes.
