A contact mechanism for use with a switch has at least two spaced stationary electrical contacts. The contact mechanism includes a rolling contact member. The contact mechanism moves between a circuit closed position where the rolling contact member electrically joins the stationary electrical contacts, and a circuit open position where the rolling contact member does not join the stationary electrical contacts.

Contact mechanism for a switch

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 complete 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.
