摘要:
An electrical switch comprises a housing, at least one fixed contact and a moving contact assembly provided in the housing, and an actuator. The actuator is supported for movement to move the contact assembly into contact with and out of contact from the fixed contact. The contact assembly comprises at least one pair of pivotable levers, with a first lever arranged to make or break contact with the fixed contact and a second lever pivotable by the actuator to in turn pivot the first lever into contact with the fixed contact.

A circuit breaker with a push button includes an electrical breaker having a casing having an opening defined therein with a hole defined in each side near the opening. A first prong and a second prong each attached to and extending through the casing. An alloy plate is attached to the first prong and has a free end aligning with the second prong. A seesaw switch is pivotally mounted in the opening of the casing with a shaft extending from the center of each side. Each of the shafts is received in the corresponding hole in the casing. A push block is pivotally attached to the bottom portion of the seesaw switch and has a recess defined therein to receive the free end of the alloy plate. An activation block extends from a top portion of the seesaw switch. A push button is attached to the electrical breaker and has an activation rod movable back and forth therein. The activation rod presses on the activation block of the seesaw switch and has an axis at a right angle with the axis of the shaft.

A dual function electrical switch which can be operated either as a three position toggle switch or as a push button switch. The switch includes an elongated plunger-equipped actuator or operating shaft mounted within a casing, a toggle lever blade rockably mounted within the casing below the plunger, and a pair of switch levers pivotally mounted within the casing on opposite sides of the actuator. Each of the levers are engageable with one or more terminals which are mounted within the casing and extend outwardly therefrom. A pair of spring-biased plungers are carried by a cross shaft extending transversely through the actuator shaft and push the switch levers into electrical contact with their associated terminals when the actuator shaft is depressed longitudinally downwardly. When the actuator shaft is not depressed, it is pivotable out of its centered position to operate the toggle lever blade. Abutment means carried by the actuator shaft are cooperable with an opening in the top wall of the casing to prevent toggling action when the actuator shaft is depressed and to prevent push button action when the actuator shaft is pivoted. A flexible sealing boot hermetically seals the interior of the casing during both toggling and push button action.

A lever operated electric switch has a rocker that is tilted to one side or the other from an intermediate neutral position by movement of the lever. The rocker engages one arm or the other of a leaf spring type of contact member causing engagement with one or another fixed contact. The ends of the arms are reversely bent doubly into S-sahpe so that the extremity presents a longitudinal surface which wipes over the fixed contact surface. The ends are also bifurcated and laterally dished into trough shape.
