Abstract
The present invention provides a switchable pressure activated electronic device. The switchable electronic device includes a composite material disposed between two conductors. The composite material electrically connects the two conductors when pressure is applied between them, and electrically isolates the two conductors when pressure is not applied between them. The composite includes conductive particles at least partially embedded in an insulating material. The conductive particles are disposed so that substantially all electrical connections made between the first and second conductors are through single particles.
