MULTIPLE DETENT MEMBRANE SWITCH

摘要

An improved membrane switch includes multiple detents. A pair of electric circuits are completed by the membrane switch. The switch includes the pair of open electric circuits, three flexing areas, and two membrane contacts. Normally the flexing areas bias the membrane contacts out of contact with the electric circuits. When a first actuation force is applied to the membrane, the intermediate flexing area flexes allowing the first circuit to be completed by the first membrane contacts. When a second actuation force is applied to the membrane, the center and outer flexing areas flex allowing the second circuit to be completed by the second membrane contacts. The inventive membrane switch provides the operator with a clear indication and a detent feel for each of the two circuits.
