Method of making flexible pressure sensitive switch
First Claim
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.

Abstract
A flexible, self-biasing switching element is disclosed herein for closing a circuit by flexing the element from an initial non-contacting position to a second contacting position and for opening the circuit by releasing the element and permitting it to return to a non-contacting position from the contacting position. The element includes a flexible non-conductive substrate having on one side thereof a plurality of spaced conductive contacts or areas. A two-sided pressure sensitive adhesive film for mounting the element is die cut and applied to the substrate in a manner so as to surround the conductive contact areas. The adhesive film provides an insulating medium between the contact points so as to prevent transmission of current between the contact points.
