Abstract
An improved membrane switch includes multiple detents. A pair of electric circuits are completed by the membrane switch, and a pair of flexing portions are located on said membrane. A first flexing portion is overcome by a first lower insertion force to allow a first circuit to be complete, and a second flexing portion is only overcome by further insertion force. The second flexing portion is eventually overcome and completes a second circuit. The inventive membrane switch provides the operator with a clear indication and a detent feel for each of the two circuits.
