ABSTRACT:
A flexible touch-sense switch includes a force sensitive composite and an at least one proximity sensor. The force sensitive composite includes a plurality of force sensors disposed between a first layer and a second layer of polymide film defining a displacement region. The at least one proximity sensor generates an electromagnetic field that defines a detection region. The force sensitive composite and the at least one proximity sensor are mounted to the first layer of the polymide film for forming a flexible printed circuit board. A control circuit is electrically connected to the force sensitive composite and the at least one proximity sensor for selectively controlling the touch-sense switch activation in response to coincident actuation thereof.
