ABSTRACT:
A custom prototype membrane switch panel, kit, and method for construction. Two membranes, an insulative spacer for use therebetween, and a plurality of conductive elements disposable between each membrane and spacer are provided. Spacer apertures in registry with the elements permit electrical contact therebetween upon displacement of one membrane toward the other. The elements are comprised of conductive ink bonded to an insulated backing in any desired geometric shape or shapes, and may be provided individually or plurally in sheet form separable therefrom for disposition between the spacer and membranes. Elements of different colors facilitate tracing different conductive paths created thereby in the resultant switch panel, and the backing automatically electrically insulates crossovers between the elements. One or more of the membranes or spacer has features, alone or in combination, of transparency, having a graphic grid network superimposed thereon, or being hingable to one or more remaining membrane or spacer, facilitating aforementioned registration.
