A contactor includes a first actuator, a compressive element moveably coupling the first actuator to a rigid portion of the contactor, a shaft configured to move toward the rigid portion when the contactor is in an energized state and to move away from the rigid portion when the contactor is in a de-energized state, a second actuator fixedly coupled to the shaft, and a common contact extending between the first actuator and the second actuator, the common contact being moveable with respect to a first contact, wherein the compressive element is configured to press the first actuator against the common contact, and wherein the first actuator is configured to electrically connect the common contact and the first contact when the contactor is in the de-energized state, and the second actuator is configured to electrically disconnect the common contact and the first contact when the contactor is in the energized state.

A magnetic electrical switch apparatus includes: a switch assembly that includes: a switch body housing including a stationary contact; a shaft configured to move relative to the switch body housing, the shaft including: a moveable contact; and a first magnet; and a movable support member including a second magnet. The moveable contact and the first magnet are configured to move with the shaft. Moving the movable support member moves the second magnet relative to the first magnet, and a magnetic interaction between the second magnet and the first magnet moves the moveable contact relative to the stationary contact to thereby change a state of the switch assembly.

Disclosed is a rotary bridge micro-switch. The rotary bridge micro-switch comprises an insulating base, wherein a first terminal, a second terminal and a third terminal are arranged on the insulating base and are spaced from one another by the insulating base; and the insulating base is rotatably connected to a conducting plate having one end abutting against the first terminal. The rotary bridge micro-switch further comprises a spring having two ends respectively connected to the other end of the conducting plate and the insulating base. When the spring is not compressed, the first terminal is connected to the second terminal through the other end of the conducting plate. When the spring is compressed, the first terminal is connected to the third terminal. The rotary bridge micro-switch can be pressed to realize switching between two circuits.

A switching device includes a housing, an operation member, a plurality of fixed contacts, a plurality of movable contacts, and a snap action mechanism for causing the movable contacts to operate. The snap action mechanism includes a plurality of first drivers in each of which a fulcrum that serves as a pivot point is formed on one end side of a given first driver and in which a given movable contact from among the movable contacts is provided on another end side of the given first driver; a second driver in which a pressing member to be pressed through the operation member is formed on one end side of the second driver and in which fulcrums that serve as pivot points are each formed on another end side of the second driver; and a coupling member integrally coupling the plurality of first drivers to constitute a first drive member.

An electrical control mechanism having a support.

First return means are interposed between the central body and the button, with second return means being interposed between the central body and the support. Two primary electric switches are interposed between the button and the central body on either side of a plane containing the central axis of rotation (AXROTC) and the offset axis of rotation (AXROTD). Two secondary electric switches are interposed between the support and the central body on either side of the plane.

A switch device capable of safely opening or short-circuiting an electrical circuit in response to an abnormality such as wetting with water or liquid leaking from a battery is provided. The device includes a conductor connected to an external circuit, and a reaction part including a liquid-soluble material which opens the conductor and the external circuit and which dissolves on contacting a liquid entering the device interior to electrically connect the conductor and the external circuit.
