A circuit breaker, comprising a housing (100), an input-side wiring terminal (111) and an output-side wiring terminal (112) which are positioned on the housing, and a moving contact (202) and a stationary contact (201) which are positioned in the housing. A passage (300) is arranged in the housing between two wiring terminals to be connected with a conductor (400), and the conductor connected with the two wiring terminals is arranged in the passage. Therefore, the present invention has the advantages of simple wire connection, good safety, space saving, beautiful appearance and clear and accurate indication of the switch state.

A terminal connecting mechanism for a molded case circuit breaker that does not need a tool for connection or release between a wire and a terminal is disclosed. The terminal connecting mechanism of a molded case circuit breaker comprises a supporter having a through hole portion for allowing passing through of a terminal of the molded case circuit breaker and a terminal seat portion where the terminal, which has passed through the through hole portion, is mounted; a spring of which one end is supported by the supporter; and a lever member being in contact with the other end of the spring, rotataby moving to a position for allowing insertion of a wire to contact the terminal, and pressurizing the wire by means of an elastic force of the spring to maintain a contact state between the wire and the terminal.

The invention relates to a switch having a switch housing, a number of module-type individual interrupter chambers which can be arranged in particular side by side in the switch housing and having at least two switching contact elements, and an actuating device which closes off the switch housing above the individual interrupter chambers. This actuating device serves to adjust a cam element for the selective establishment of an electrical connection between the switching contact elements of an individual interrupter chamber. The switching contact elements can be arranged in at least two different orientations in each individual interrupter chamber in an explosion-protected manner. Furthermore, in particular the cam element of the actuating device can be arranged differently depending on the orientation of the switching contact elements. This results in a switch with a simple adaptation option for housing installation or front-panel mounting, wherein all requirements for explosion protection are also fulfilled at the same time.

A disconnector includes: a switch having: a first, fixed contact terminal of a first conductor, a second, fixed contact terminal of a second conductor, and a moveable bridge contact moveable between a first position and a second position; and an actuating mechanism having: a cam follower coupled to the moveable bridge contact and including a following surface, a cam having a cam surface, the cam surface engaging with the following surface, the cam being rotatable around an axial direction relative to the cam follower. At least one of the following surface and the cam surface includes an angled portion, the angled portion angled with respect to the axial direction such that rotation of the cam urges the cam follower in the axial direction, the cam follower moving the moveable bridge contact in the axial direction from the first position to the second position in response to the urging.

A modular switching contactor arrangement for use in a safety-oriented application, has two switching contactor modules that can be arranged in succession by means of a coupling module, the switching contactor modules and the coupling module merely having to be joined together by a user, without any external wiring, so as to be mechanically and electrically coupled to one another. In the mounted state, the switching contactor arrangement has a reduced construction width that is substantially delimited by the narrow faces of the switching contactor modules. In particular, the construction width can be 22.5 mm.

A modularized structure of switch wire connection device includes an assembling support and a wire connection module. The assembling support has a first side and a second side. The first and/or the second sides are formed with assembling sections for assembling with the wire connection module. The wire connection module includes a first wire connection module and/or a second wire connection module each having a case. The case defines a chamber for receiving and enclosing electrical contact components including conductive members. The case is formed with a mounting section for connecting with the assembling section of the assembling support. Accordingly, the wire connection module is detachably mounted on the assembling support as an integrated form. The modularized structure enables an operator to easily assemble/disassemble the components and change the switch specification between normally open mode and normally closed mode and enhance insulation effect to avoid electric arc.
