Abstract: A manual operator for a pushbutton control device includes a cover having protected space surrounding an opening receiving the pushbutton. The cover further includes a raised stop surface adjacent the protected space. A lever actuator is pivotally mounted to the cover so as to concurrently overlie the pushbutton and the stop surface when in a nonoperating position. The actuator is moved into alignment with the protected space and is depressed to assume an operating position.

Abstract: An electrical switch of the type actuated by depressing a spring-loaded plunger functions as a bi-directional limit switch. It utilizes a lever mechanism having two fulcrum points on opposite sides of the plunger. Deflection of the switch lever arm in either direction depresses the switch plunger.

Abstract: A toggle lever for operating an electric switch and easily assembled, anti-rotation means for mounting the lever for limited pivotal movement within the mounting bushing of the switch. The toggle lever has an intermediate enlarged spherical portion including two short trunnions extending in opposite directions therefrom. The mounting means comprises a pair of interlocking semi-cylindrical molded insert halves having on their inner surfaces an annular socket for the spherical portion and each having a central hole to journal the corresponding trunnion when the two halves are placed therearound to form a subassembly.

Abstract: A switch, and a dual lamp and switch combination comprising two conductive strips spaced from each other and each having a contact point adjacent an upper end. The conductive strips contacting filament wires of the lamp or electrical conductors of a power line. A handle including a base is pivotably mounted relative to the contact points, and a conductive member operated by the handle, selectively contacts at least one of the contact points. The conductive member is integral with at least a portion of the conductive member and engages a metallic screw-on section of the lamp or electrical conductors of the power line.

Abstract: A push-push type of switching apparatus having a push rod movable in a slideway on one face of a flat mounting bracket. A snap switch is mounted on the opposite face of the bracket. A pivotable actuating lever extends transversely through the bracket. The lever has one paddle portion in the slideway in the path of the push rod and a spaced second paddle positioned over the actuator of the snap switch. Depression of the push rod displaces the first paddle out of the path of the rod and pivots the lever. Pivoting of the lever causes the second paddle to depress the actuator button of the snap switch.

Abstract: An array of curved metal strips is supported over an array of conductors, and a key is supported over each intersection of a metal strip and a conductor. When a user depresses a key, a metal strip is pressed against a conductor to make an electrical connection. As the metal strip is deflected by the key, it snaps or buckles, providing tactile feedback to the user.
