Abstract: A vehicle control switch assembly for use with a printed circuit board that includes a switch having an elastomeric pad portion and a first insert interface attached to the pad. The assembly also includes first and second electrical contacts, each contact being selectively operable to actuate a vehicle function. The switch assembly also includes a pivotable beam member bridging a span between the first electrical contact and the second electrical contact. Movement of the switch in a first direction causes the first insert interface to depress the beam member thereby engaging the first electrical contact with the printed circuit board to actuate the first electrical contact. Further movement of the switch in the first direction causes the first insert interface to slide along the beam member in a second direction to further depress the first beam member thereby actuating the first electrical contact and the second electrical contact.

Abstract: A micro-electromechanical (MEM) RF switch provided with a deflectable membrane (60) activates a switch contact or plunger (40). The membrane incorporates interdigitated metal electrodes (70) which cause a stress gradient in the membrane when activated by way of a DC electric field. The stress gradient results in a predictable bending or displacement of the membrane (60), and is used to mechanically displace the switch contact (30). An RF gap area (25) located within the cavity (250) is totally segregated from the gaps (71) between the interdigitated metal electrodes (70). The membrane is electrostatically displaced in two opposing directions, thereby aiding to activate and deactivate the switch.

Abstract: A key operation detection unit of an electronic keyboard instrument that suppresses increase in reaction forces with key depression operation, to improve a key touch feeling. A depression operation of any one of keys of the keyboard instrument is detected by first and second corresponding detectors of the detection unit. The detectors are surrounded by an outer resilient projection and each comprised of an inner resilient projection and a movable portion extending therefrom toward a base plate of the unit. With key depression, the movable portion of the first detector is in contact with the base plate and its inner resilient projection is deformed to generate a reaction force. With further key depression, the inner resilient projection of the second detector brought in contact with the base plate is deformed to generate a reaction force smaller than the reaction force from the first detector.

Abstract: Apparatus for a micro-electro-mechanical switch that provides for latching switching action. The switch has a cantilever arm disposed on a substrate that can be moved in orthogonal directions for latching and unlatching. To latch the switch, the cantilever arm is moved back by a comb-drive actuator and then pulled down by electrodes disposed on the substrate and the cantilever arm. The comb-drive actuator switch is then released and the cantilever arm moves forward to be captured by a dove-tail structure on the substrate. When the voltage to the electrodes on the substrate and the cantilever arm is removed, the cantilever arm is held in place by the dove-tail structure. The switch is unlatched by actuating the comb-drive actuator to move the cantilever arm away from the dove-tail structure. The cantilever arm will then pop up once it is released from the dove-tail structure.
