Claims
- 1. A method for manufacturing a unitary, self-biasing and flexible switching element which includes a flexible and electrically non-conductive substrate, a plurality of electrically conductive contact area means carried by the substrate, indicia carried by said substrate and in aligned relation to said contact area means so as to indicate individual contact areas which may be activated, and apertured insulating and bonding means carried by said substrate and in surrounding relationship with each of said contact area means, said method including the steps of:
- providing flexible and electrically non-conductive substrate;
- printing said contact area means on one side of said substrate with silver; and
- applying said apertured insulating and bonding means to the same side of said substrate as said contact area means and in surrounding relationship to said contact area means so as to insulate contact area means from one another and so as to permit said element to be bonded to a surface.
- 2. A method as in claim 1, wherein said indicia is a decorative ink layer and said method further includes the step of printing said ink layer on said substrate.
- 3. A method as in claim 2, wherein said ink layer is printed on the same side of said substrate as said contact area means and where the ink layer is printed on said substrate prior to the printing of said contact area means so that said contact area means are subsequently printed on said ink layer means.
- 4. A method as in claim 3, wherein said substrate is transparent and said indicia is visible therethrough.
