Abstract
A switch mechanism (12) includes a housing (16, 18) with a fenestration (21), a switch element (22) held in the housing, and a membrane switch held in the fenestration. The membrane switch includes a flexible membrane (20) and a rigid rib (26). The rib is constrained to linear movement by guides (37, 38) in the housing so that contact with the membrane causes the membrane to deform and the rib to translate to actuate the switch element.
Claims15
A switch mechanism comprising:
- a housing, where the housing comprises a fenestration, a lip, and a plurality of guides;
- a switch element held in the housing;
- and
- a membrane switch, the membrane switch being held in the fenestration and including a flexible membrane, a rigid rib, and a button extending between the rigid rib and the switch element, the flexible membrane including:
- a first side defining an outer surface of the switch mechanism and an opposing second side, the rigid rib disposed within the housing and adjacent to the second side of the flexible membrane;
- and
- a tab portion configured to engage with the housing lip and the rigid rib;
- wherein the rigid rib is constrained to linear movement along the plurality of guides so that a contact with the flexible membrane is configured to cause the flexible membrane to deform and the rigid rib to slide along the plurality of guides and provide a translational planar motion displacement of the rigid rib relative to the plurality of guides to actuate the switch element via the button.

The switch mechanism of 3 wherein the flexible membrane supports off center activation of the switch mechanism.
A switch mechanism comprising:
- a housing, where the housing comprises a fenestration, a lip, and a plurality of guides;
- a switch element held in the housing;
- and
- a membrane switch, the membrane switch being held in the fenestration and including a flexible membrane, a rigid rib, and a button extending between the rigid rib and the switch element, the flexible membrane including:
- a first side defining an outer surface of the switch mechanism and an opposing second side, the rigid rib disposed within the housing and adjacent to the second side of the flexible membrane;
- and
- a tab portion configured to engage with the housing lip and the rigid rib, wherein the rigid rib includes a plurality of recesses that receive and directly contact the plurality of guides in a mating relationship;
- and
- wherein the rigid rib is constrained to translational planar motion displacement of the rigid rib along the plurality of guides so that a contact with the flexible membrane is configured to cause the flexible membrane to deform and the rigid rib to move to actuate the switch element via the button.

A switch mechanism comprising:
- a housing, where the housing comprises a fenestration and a plurality of guides;
- a switch element held in the housing;
- and
- a membrane switch, the membrane switch being held in the fenestration and including a flexible membrane, a rigid rib, and a button extending between the rigid rib and the switch element, the flexible membrane including a first side defining an outer surface of the switch mechanism and an opposing second side, the rigid rib disposed within the housing and adjacent to the second side of the flexible membrane;
- the rigid rib being constrained with the housing such that, based upon contact with the flexible membrane by a user, the rigid rib is constrained to pivotal movement by fulcrums in the housing such that the rigid rib moves relative to at least one of the guides to allow the flexible membrane to deform and the rigid rib to move relative to housing, to allow a displacement of the rigid rib along the at least one guide, to actuate the switch element via the button, wherein the rigid rib is constrained by the fulcrums such that contact with the flexible membrane causes the flexible membrane to deform and the rigid rib to rotate about one of the fulcrums to actuate the switch element.
