Abstract: A pivot switch assembly including a button and a housing. The housing includes a trunion and a retaining wall. The trunion opposes the retaining wall and forms a receiving gap between the two features. The button includes a rib. The rib has an aperture. The rib of the button being positioned into the receiving gap of the housing. The trunion of the housing then engages the aperture of the rib of the button so as to provide a pivoting function for the switch assembly. The geometry of the button and housing prevents the button from becoming dislodged during periods of high acceleration, such as during deployment of an airbag.

Abstract: A submersible, touch-operated signaler including at least a pair of facially confronting, electrically conductive plates. Strips of resilient, nonconductive material are interposed between the plates to maintain a substantially preset spacing therebetween and to yieldably resist movement of the plates toward each other. The strips are disposed in a plurality of vertically aligned and spaced rows with vertically aligned fluid-draining passages therebetween. Rigid edge containment brackets along adjacent margins of the plates secure the edges of the plates against movement away from each other. Openings extend through a rear electrically conductive plate which align with the vertically oriented passages between the resilient strips to provide free vertical fluid flow into and out of the space between the plates. The touch-operated signaler operates on low voltage.

The connecting trunk, the first connecting member, the independently actuatable button, the second connecting member, the torsion bar, and the independently actuatable rocking switch are all integrally formed and actuating the independently actuatable rocking switch does not affect the independently actuatable button.

Abstract: A method and apparatus for controlling the flow of signals by selectively switching signals to ground and allowing signals to pass through a signal line based a position of a conductive pad. The switch contains waveguides including the signal line and at least one ground plane. The conductive pad responds to an actuation voltage to electrically connect the signal line and the ground planes when the metal pad is located in a relaxed position. When not located in the relaxed position, the switch breaks the connection to allow signals to flow through the signal line unimpeded. Brackets guide the pad as the pad moves between the relaxed position and a stimulated position due to the actuation voltage, without substantially deforming the conductive pad.

Abstract: An improved multiple-width keyswitch capable of inhibiting noise thereof induced during operation is provided. The multiple-width keyswitch includes a keycap and a substrate. During operation, the keycap moves vertically relative to the substrate. The keycap defines a lower surface which is provided with a plurality of bosses. The substrate is provided with a plurality of openings. Each of the plurality of openings is disposed under one corresponding boss and covered with a deformable layer. When the keycap moves downward to turn on the keyswitch, each of the bosses first impacts the deformable layer into the corresponding opening such that the impact energy of the keycap is absorbed by the deformable layer. Thereby the noise induced by the impact of the keycap can be effectively inhibited. Embodiments and equivalent modifications of the invention are described in detail in the specification.
