Embodiment Construction

[0050] Figures 1 to 3 An embodiment of a switching device 10 according to the invention is shown. In principle the components of this embodiment are all the same. The switching device 10 therefore has a rotor housing 20 which is provided with two contact arms 22 . The contact arms are arranged on opposite sides of the rotor housing 22 and each have a movable contact 24 . exist figure 1 In this case, ie in the OFF position of the switching lever 32 , the movable contact 24 is separated from the stationary contact 12 opposite it, so that the rotor housing is in the disconnected position O. exist figure 2 The rotor housing 20 is rotated in such a way that the movable contact 24 is arranged in conductive contact with the stationary contact 12 and the rotor housing 20 is thus in the closed position S .

[0051] In addition, the switching device 10 according to the invention has a switching unit 30 . The switching unit 30 has as a main component a switching lever 32 which p...

Abstract

The invention relates to a switching device for an electrical switching device, in particular a compact circuit breaker, having a rotor housing which is rotatable between an open position and a closing device and has at least one contact arm with a movable contact. head, the movable contact is in conductive contact with the fixed contact of the switch device in the closing direction; the switch device has a switch unit, which has a switch lever that can move between the on position and the off position and The switch frame, the linkage mechanism is in operative contact with the switch frame and the rotor housing, so that the rotor housing can be moved into the closed position by the switch lever movement into the on position and by the switch lever The rotor housing can be moved into the disconnected position, the linkage has at least one stop, which is designed to prevent the switching lever from moving independently of the rotor housing when the rotor housing is in the closed position. In the case of body movement, move into the disconnected position.

Description

technical field [0001] The invention relates to a switching device for an electrical switching device, in particular a compact circuit breaker, and to such an electrical switching device. Background technique [0002] Switching devices for electrical switching devices and such electrical switching devices are known in principle. In order to be able to make and break an electrical circuit, such switching devices often have a rotatable rotor housing, which can be rotated between an open position and a closed position. In the closed position, the contacts are electrically conductively connected to each other, while in the open position they are separated from each other with insulation. In addition, known switching devices provide a switching unit which can be moved by means of a switching lever at least between an ON position and an OFF position. A linkage is often provided between the switch unit and the rotatable rotor housing, which linkage converts movement between an ON...
