A housing assembly is for an electrical switching apparatus. The electrical switching apparatus includes an arc chute and a collar. The housing assembly comprises: a plurality of housing members comprising a first base member and a second base member, the first base member being structured to receive the collar, the second base member being coupled to the first base member and being structured to receive the arc chute. The first base member is made from a first material and the second base member is made from a second, different material.

Disclosed is a molded case circuit breaker including a case configured to accommodate an element for trip, an upper cover detachable attached to the case, a dial configured to include a fixing plate, which is provided to protrude along an outer circumference surface thereof, and a first stopper disposed under the fixing plate, a crossbar moved by the dial, a first dial fitting hole provided in the upper cover for the dial to be fitted into the first dial fitting hole, and a dial rotation adjusting unit provided in the first dial fitting hole and fitted between the fixing plate and the first stopper to guide a rotation of the dial, the dial rotation adjusting unit including a plurality of fitting grooves arranged at certain intervals. The first stopper is fitted into and fixed to the plurality of fitting grooves according to the rotation of the dial.

A circuit breaker includes a main body case, an operating handle having a base portion and a knob portion protruding outwardly through a handle window frame opened in a cover of the main body case; a first shutter arranged between the base portion of the operating handle and the handle window frame, and disposed on the base portion, the first shutter being formed with a loose-fit hole to loosely fit the knob portion therethrough; and a second shutter disposed on the first shutter to move along with the knob portion. At ON and OFF positions of the operating handle, the first shutter extends beyond a front/rear edge of the handle window frame in a front-back direction to close the handle window frame, and the second shutter extends beyond a front/rear edge of the loose-fit hole in the front-back direction to close the loose-fit hole.

An interface assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing, a first handle partially extending through the housing, separable contacts located within the housing, an operating mechanism to open and close the separable contacts, a main printed circuit board located within the housing, and a number of electrical rating settings associated with the main printed circuit board. Each of the electrical rating settings has a magnitude. The interface assembly includes: a base assembly comprising a base, the base being disposed on the housing, the base having a mounting surface; and a second handle coupled to the mounting surface, the second handle and the first handle being structured to drive each other. The mounting surface has at least one port. The magnitude of a corresponding one of the electrical rating settings is visible through the at least one port.

An electromagnetic contactor includes a contact device having a pair of fixed contacts disposed to maintain a predetermined distance and a movable contact disposed so as to contact to and detach from the pair of fixed contacts. An insulating cover, which covers the pair of fixed contacts except for contact portions that contact the movable contact and covers an inner surface of an insulating plate that fixes and holds the fixed contacts, is mounted on the pair of fixed contacts.

An emergency button for a vehicle used for emergency rescue when a vehicle accident or an emergency situation occurs has a design structure reflecting a design to prevent an erroneous operation for conforming to governmental regulations, and an intuitive human-machine interface (HMI) to allow a user to easily operate the emergency button and prevent an erroneous operation from being generated. The emergency button includes a case; a cap coupled to an upper portion of the case so as to move up and down during rotation; and a button part which is interfered in a rotation direction and slidably coupled with the cap to be rotated together with the cap, receives elastic support by a spring at a lower side to be movable up and down, and is in contact with the switch for transmitting a call connection signal within the case to transmit a call connection signal.

A switch assembly that includes a cutout mounted fault interrupting switching device and ice shields that block ice build-up on the assembly that may otherwise impede a dropout operation of the switching device. The switching device includes a switch, an upper electrical contact and a lower electrical contact. The switch assembly includes an upper coupling assembly configured to releasably engage the upper electrical contact and a lower coupling assembly configured to engage the lower electrical contact in a pivoting engagement, where the switching device is operable to pivot relative to the lower coupling assembly when the upper electrical contact is released from the upper coupling assembly. The switch assembly further includes an upper ice shield coupled to and formed over the upper coupling assembly and a lower ice shield coupled to and formed over the lower coupling assembly.

Systems and techniques are provided for an interchangeable back system for programmable switches. A programmable switch, remote interchangeable back, and toggle switch interchangeable back may be included. The remote interchangeable back may include a casing and a back plate, where the back plate of the remote interchangeable back may not have an opening. The toggle switch interchangeable back may include a casing and a back plate, where the back plate of the toggle switch interchangeable back may include an opening of sufficient size to accommodate a toggle light switch in the on position. The remote interchangeable back and the toggle switch interchangeable back may be interchangeably attachable to and removable from the programmable switch.
