Abstract: A switch assembly having a sliding actuator adapted to be moved by a cam on a stalk lever. Initial movement of the actuator from a neutral position by user movement of the lever moves a first contact carried by the actuator to break a connection between a power bus and a fog lamp terminal strip in a planar array of strips. Further movement causes a second contact carried by the actuator to make a connection between another power bus strip and a high beam terminal strip. Continued movement of the sliding actuator causes rotational movement of a bi-stable rotor latched in one of its two bi-stable positions. Movement of the rotor causes a third contact on the rotor to shunt the second contact to make a second connection on another high beam strip and a fourth contact on the rotor breaks a second connection on the strip for the fog lamp electrically in series with the first connection.

Abstract: A notebook computer is provided with a collapsible keyboard structure in which, during operation of the computer, the keys are held in extended operating positions by the force of a pressurized fluid-filled flexible mat member having spaced apart orificed compartments against which bottom ends of vertically movable plunger portions of the keys downwardly bear. Position sensors monitor the stroke positions of the keys and, as the keys are depressed during computer use, responsively transmit corresponding position signals to a control system which utilizes the position signals to alter the fluid pressure within the mat member in a manner providing the keys with predetermined, selectively variable stroke force/distance characteristics. When the computer is turned off, fluid pressure within the mat member is relieved in a manner permitting the keys to collapse to retracted storage/transport orientations, thereby reducing the overall thickness of the keyboard until subsequent operation of the computer.

Since many fixed contacts are not only disposed on the printed wiring board but also on the casing, the printed wiring board can be designed compact. Also the plurality of fixed contacts disposed on the casing has such a form of a terminal as to be electrically connectable to motors and a power source as well as to a connector extended to the switching device. Therefore, the number of places to be soldered for electrical connection between many fixed contacts, motors and power source can be reduced.
Abstract: The invention includes a mechanism for multi-dome switch having first, second, third and fourth collapsible dome structures. An elongated action bar extends across and bridges a pair of collapsible dome structures. The action bar, each have a top surface and a bottom surface. A notch is formed in the top surface closer to one of the dome structures. Engagement nubs extend downwardly from the bottom surface of the action bar near both ends and are positioned to be received in a respective depression formed on the top surface of the collapsible dome. A switch pedal is positioned for pivotal movement between a first and second forward positions, and a first and second backward (rear) positions.
