An electrical switch including a frame, an operating shaft, and a bridge member movable in a depth direction relative to the frame by rotation of the operating shaft, wherein the depth direction is parallel with a rotation axis of the operating shaft, and wherein the operating shaft is adapted to exert a first opening force to the bridge member during an opening event. The electrical switch includes an anti-tilting member movable in a lateral direction relative to the frame by rotation of the operating shaft, the lateral direction being perpendicular to the depth direction, wherein the anti-tilting member is adapted to exert a second opening force to the bridge member during the opening event, the second opening force being parallel to the first opening force and spaced apart from it in the lateral direction.

A high-durability electrical contact structure may include a first contact and a second contact disposed to face each other while being spaced apart a predetermined distance from each other. A portion of the second contact includes a magnetic material. Damage to the surfaces of an arcing electrical contact according to arc generation positions between contacts is minimized, increasing the life of the arcing electrical contact.

The electromagnetic relay comprises an auxiliary fixed terminal that has a configuration different from that of a fixed terminal and includes an auxiliary external input/output terminal and an auxiliary external output/input terminal that can be electrically connected to the auxiliary external input/output terminal. The electromagnetic relay comprises an auxiliary movable terminal that has a configuration different from that of a movable terminal and can electrically connect the auxiliary external input/output terminal and the auxiliary external output/input terminal.

A shunt trip assembly is structured to be operatively coupled to a number of circuit breakers. The shunt trip assembly includes a housing assembly and an actuating assembly. The actuating assembly includes a limited number of components. In another embodiment, the shunt trip assembly housing assembly is a substantially sealed housing assembly. In another embodiment, the shunt trip assembly housing assembly includes a single mounting panel.

A circuit breaker includes a first fixed contact and a first movable contact which can be switched between a closed status and a tripped status, a signaling device for signaling when the circuit breaker is in a tripped status, a trip actuator movable from an initial position to an end-stroke position when the first movable contact is switched from the closed status to the tripped status, a tripping bar which is connected to the first movable contact so as when the trip actuator moves from the initial position, the tripping bar moves and triggers switching of the first movable contact from the closed status into the tripped status, and a trip member having a single-piece shaped body, which includes a first portion actuated by the trip actuator, a second portion spaced apart from the first portion, and a third portion spaced apart from the first and second portions.

An electromagnetic relay includes a movable element, a movable yoke, a fixed yoke, a movable section, and a stopper. The movable element includes a movable contact point. The movable yoke is connected to the movable element to move together with the movable element. The movable section includes a movable core made of an inorganic magnetic material and a shaft made of an inorganic material. The fixed yoke is made of an inorganic magnetic material and disposed between the movable core and the movable yoke. The stopper protrudes from either one of the fixed yoke or the movable section toward the other to contact with the other when the movable section moves toward the fixed yoke. The stopper is integrally formed with the either one of the fixed yoke or the movable section.
