A push switch includes a movable contact member, a first fixed contact, and a second fixed contact. The push switch is in a first contact state in a first contact position where the movable contact member contacts the first fixed contact, and is in a second contact state in a second contact position where the movable contact member contacts the second fixed contact. The push switch is not switched to an on state in response to transitioning from an off state to the first contact state, and is switched to the on state in response to further transitioning to the second contact state, and the push switch is not switched from the on state to the off state in response to the second contact state being released, and is switched from the on state to the off state in response to the first contact state being further released.

Embodiments included herein are directed towards an apparatus for actuating a switch of an operator control device, and related methods. Embodiments of the present disclosure may include a trigger shaped to mate with the operator control device. The trigger may include an integrated preload portion formed, at least in part, within the trigger. The trigger may further include an integrated actuator portion formed, at least in part, at an interfacing portion of the trigger. The integrated actuator portion may be configured to interface with the switch of the operator control device.

A switch device according to one or more embodiments is disclosed that may include a pressing member, an urging member, fixed contacts, at least one movable contact swingable in a direction intersecting with a movement direction of the pressing member and connecting and disconnecting between the fixed contacts.

The pressing member includes a slider portion extending in a direction oblique to the movement direction and slidable along the movable contact. The movable contact is pressed by the slider portion in the pressing member sliding to swing and come in contact with and separate from at least one of the fixed contacts in response to the pressing member moving from a reference position to a pressed position.

A vacuum circuit breaker comprises a vacuum interrupter operable between a closed state and an open state, and an actuator. The actuator comprises a piezoelectric driving element that is expandable and contractable along an expansion axis in response to an electrical input signal. The actuator further comprises a mechanical amplifying structure extendable along an actuation axis and being mechanically coupled to the piezoelectric driver such that expansion or contraction of said piezoelectric driving element causes the amplifying structure to extend or retract along the actuation axis. The mechanical amplifying structure is coupled to the vacuum interrupter for operating the vacuum interrupter between said closed and open states.

An electronic switch includes a rubber sheet that includes a first surface, a second surface opposite to the first surface, and a convex portion on the first surface. The convex portion of the rubber sheet includes a semispherical shape.

A switching mechanism includes an actuator rotatable between an off position and an on position; and a timing disc assembly that includes an actuator disc, a bias disc, and a switch disc arranged in a stack. The actuator disc is rotatably connected to the actuator. The bias disc is connected to at least one biasing mechanism. The switch disc is connected to a switch. The actuator disc is configured to engage the bias disc such that the actuator disc is configured to rotate the bias disc to an overcenter position of the at least one biasing mechanism. The overcenter position of the at least one biasing mechanism is configured to rotate the bias disc such that engagement between the bias disc and the switch disc is configured to rotate the switch disc between a closed position and an open position of the switch.
