The contactor further includes a rotatable member rotatable about a central axis, with the movable contact being mounted thereon. The rotatable member is rotatably mounted on a support plate. Two ceramic members are mounted on the support plate, with each defining an internal region. Two permanent magnets are mounted on the support plate and located outside of the two ceramic members, respectively. The two ends of the movable contact are located in respective internal regions of the two ceramic members, such that an electrical arc generated between the movable contact and the static contact is located within the internal region.

A residual load disconnector switch (1) includes a rotary switch body (23), which includes a contact blade (24, 25, 26, 27), that is rotatable about an axis (A) and is arranged between a feed line connection (20) and a discharge line connection (21), and includes end-side contact surfaces (28, 29, 30, 31) protruding in a radial direction.

A change-over switch including a frame having a first side wall and a second side wall, a first supply terminal, a second supply terminal, a load terminal, and at least one gas flow opening for discharging gasses from the frame. The second side wall faces substantially opposite direction relative to the first side wall. The change-over switch is adapted to selectively provide a first connection between the first supply terminal and the load terminal, and a second connection between the second supply terminal and the load terminal. The first supply terminal and the second supply terminal project from the first side wall, and the load terminal projects from the second side wall. The at least one gas flow opening is formed in the second side wall.

An electrical contact system includes a pair of static contacts, a rotatable member disposed between the static contacts and rotatable about a rotation axis between a first position and a second position, and a movable contact mounted on and rotated with the rotatable member. A pair of opposite ends of the movable contact are in electrical contact with the static contacts when the rotatable member is rotated to the first position. The ends of the movable contact are separated from the static contacts when the rotatable member is rotated to the second position. The movable contact has a Z-shape and is slidably mounted on the rotatable member. The movable contact slides under a pushing force from a first static contact of the static contacts toward a second static contact of the static contacts to be in electrical contact with the second static contact.

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.
