Claim:
1. A multi-layered electronic system comprising: a support substrate; a primary conductive track and a conductive shorting element supported by the support substrate, the primary conductive track and conductive shorting element being in electrical isolation from one another; a security layer including at least a conductive security connection and a flexible switch element providing an electrical interruption to the conductive security connection, the conductive security connection being in electrical engagement with the primary conductive track, and the flexible switch element being at least in part coplanar with the conductive security connection; and a dielectric substrate on which the security layer is provided, and which is directly or indirectly secured to the support substrate; wherein the electrical interruption of the conductive security connection is bridged by the switch element contacting the conductive shorting element under an actuation force provided from the direction of the dielectric substrate, the switch element returning to an unbiased condition out of electrical contact with the conductive shorting element in the absence of said actuation force.
