A rotor housing of an electrical switching device, in particular a compact circuit breaker, is disclosed. In at least one embodiment, the rotor housing is embodied to mount a moveable contact arm bridge and includes a first and a second rotor housing element, which can be connected in a form-fit manner to one another and which can surround the contact arm bridge at least in sections when in the connected state. An electrical switching device is also disclosed, in particular a compact circuit breaker, including a moveably mounted contact arm bridge, an opening mechanism and a rotor housing of this type for mounting the moveable contact arm bridge.

Rotor housing of an electrical switching device and electrical switching device

An electrical switch is disclosed, especially a circuit breaker. In addition, a method for improving such a switch is also disclosed. In order to protect an electrical switch in an especially simple manner from contamination and/or damage by erosion materials, it is proposed to cover a few or all functional parts of the switch at least partly with a protective material, wherein the protective material involves a viscous, temperature-resistant mass.

Electrical switch

An electric switch is disclosed. In at least one embodiment, the switch includes a rotor housing; at least one electric contact arm, rotatably mounted in the rotor housing and being pivotable between an on-position and an off-position as well as relative to the rotor housing; and at least one intermediate part which, in a locking position, locks the pivotable contact arm with the rotor housing and, in the event of a relative rotation between the pivotable contact arm and the rotor housing, is moved away from the predefined locking position.
