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.
