Abstract: An apparatus and method to minimize teasing and contact welding at contact points includes a switch having a first contact movable toward a second contact from a switch-deactuated position to a switch-actuated position and movable away from the second contact from the switch-actuated position back to the switch-deactuated position.

Abstract: A switch comprises a first and second contacts, a plunger, a toggle bar, and a spanner. A preferred trip lever arrangement is used in which a trip lever transfers an actuating force from the plunger to the toggle bar, and the toggle bar is caused to move farther than the plunger to provide a short trip point. Swing arms that are acted upon through a series of rigid body force transfers allow an operator to manually force welded contacts to be broken in the event that the contacts become welded to a spanner or other components of the switch assembly.

Abstract: A double pole, manual reset switch that is sealed from its application environment. The switch comprises a shell and a base assembly including an actuator, terminals and blade/contacts. After the switch actuator is depressed to a “make” position, it must be manually lifted back to a “break” position. The switch has an epoxy seal along the bottom between the shell and base, heat shrink material around an opening where wires pass through, and an O-ring on the actuator for sealing the top of the switch. The components of the switch are easily assembled in the base prior to insertion of the base assembly into the shell. The wires extend from the switch adjacent to each other at an end, and in an alternate embodiment of the switch, the wires extend in pairs from a rear side of the switch.

Abstract: An electrical switch incorporating a snap-acting M-blade is actuated by a lever requiring a low actuation force and is actuated by a bridge engaging a critical region of the M-blade's double-loop end to provide an extremely low differential. Together, the means for actuating cover a broad range of applications. Additional features include a snap-acting M-blade actuated by a second snap-acting device, and the lever comprising an integral tab that serves as a pivot point.

The switch simply includes a sheet metal M-blade automatically spot welded (or riveted) to a sheet metal spring arm. The spring arm has an integral tab pressed between two flexible legs of the M-blade. The stress imparted by the tab accurately distorts the M-blade so that it assumes a very predictable bistable operation.

Abstract: A push button switch, particularly a master switch, has housing-affixed contacts (4, 7) and at least one contact bridge (8, 9) movable by a spring plunger (10).

Upon alternate depressions of the sliding switch, the sliding switch alternately moves between "on" and "off" positions. In order to prevent damage to the locking apparatus upon a pulling of the sliding switch in a direction opposite to a direction of depression of the sliding switch, the first and second locking parts release from the housing to follow movement of the sliding switch.

Abstract: A hybrid switch includes a snap-action switching portion having a butterfly-type mechanism and a solid-state switching portion formed within a single, compact housing. The solid-state switching portion is formed of an electro-electronic device consisting of a light-emitting diode and a phototransistor. Alternatively, the solid-state switching portion is formed of a bipolar transistor.

Abstract: In an electrical switch having two stable contact states, e.g., a snap-acting butterfly type switch which includes a spring biased movable actuator mounted in a housing and pivotally engaged by contact carrying arms which are urged together by a tension spring, a fulcrum cooperates with each contact arm during normal operation. During movement of the actuator in a first direction, the contact arms pivot about the fulcrums and the contacts begin to move away from a first stable state. When the horizontal position of the arms is reached, the arms pivot rapidly under influence of the tension spring and the contacts "snap" to the second stable state. During the spring biased return movement of the actuator, the contact arms pivot without contact movement until the horizontal position is passed and snap-action occurs.
