An electric switch including a frame, a first stationary contact, a roll element adapted to rotate relative to the frame, a rotating contact stationary fixed to the roll element, and an arc extinguisher plate system. The arc extinguisher plate system includes at least one first arc extinguisher plate for extinguishing an electric arc generated during an opening event between the first stationary contact and a first contact portion of the rotating contact. The at least one first arc extinguisher plate is fixed to the roll element.

Electrical switch contact sets are disclosed. A disclosed example apparatus includes a movable platform having first and second contacts, where the first and second contacts electrically coupled via the movable platform, and a stationary portion having third and fourth contacts, where the movable platform is movable to bring the first and second contacts in contact with the third and fourth contacts, respectively, to simultaneously close a current path of an electrical circuit associated with the first, second, third and fourth contacts.

The invention refers to a fuse switch module (1) that comprises a casing (2) having an aperture (3) and a cover (4) for closing and opening the aperture (3), and a rotatable fuse cartridge (11) for receiving a fuse (8). The fuse cartridge (11) is rotatable between a switch module closed position in which a fuse (8) is connected with fixed contacts (5,6) to enable current circulation, and a switch module open position in which current circulation through the fixed contacts (5,6) is impeded. The cover (4) and the fuse cartridge (11) are engaged when the cover (4) is closing the aperture (3) and when the fuse cartridge (11) is in the switch closed position, thus, the cover (4) is locked by the fuse cartridge (11) and opening of the cover (4) is impeded while current is circulating through the switch module.

In an embodiment a switching device includes two fixed contacts and a rotary contact bridge in a switching chamber in a gas-tight region, wherein the rotary contact bridge is rotatable about an rotation axis, wherein, in a first switching state, the fixed contacts are electrically conductively connected by the rotary contact bridge, wherein, in a second switching state, the rotary contact bridge is rotatable about the rotation axis relative to the first switching state, and the fixed contacts are electrically insulated from one another, and wherein the gas-tight region includes H.sub.2.

A low voltage contact assembly including a rotating support having a body adapted to rotate around a rotation axis and supporting at least a first couple of movable contacts that can be coupled to/uncoupled from corresponding first fixed contacts by rotation around said rotation axis. The first couple of movable contacts include a first and a second movable contacts housed in the rotating support. The low voltage assembly further includes a pressure exerting device having a pressing bar operatively coupled to the first and second elongated contact body and transversally placed with respect to the rotation plane of the first and second elongated contact bodies.

The disclosure relates to the field of circuit breakers, in particular to an electrode for a circuit breaker and the circuit breaker, wherein the electrode includes an electrical terminal configured to input and output electrical power to the electrode, a stationary contact electrically connected to the electrical terminal and fixed to the electrical terminal, a movable contact configured to rotatably engage the stationary contact, an arc chute arranged on the electrical terminal and adjacent to the stationary contact, and a magnetic member arranged to generate a magnetic field force when the movable contact is disconnected from the stationary contact so as to push an arc formed between the movable contact and the stationary contact towards the arc chute.

Electrical switch contact sets are disclosed. A disclosed example apparatus includes a movable platform having first and second contacts, where the first and second contacts electrically coupled via the movable platform, and a stationary portion having third and fourth contacts, where the movable platform is movable to bring the first and second contacts in contact with the third and fourth contacts, respectively, to simultaneously close a current path of an electrical circuit associated with the first, second, third and fourth contacts.
