  • Low-voltage power switch with a bearing arrangement for a switch shaft
    Patent number: 6777636
    Abstract: A low-voltage power switch, includes a drive device, fixed by way of a supporting framework and an associated switch shaft, fixed by way of two axially external bearing sub-assemblies, to the switch pole sub-assembly. In order to ensure that the fitting corresponds to a position based on separate examination of the drive device, the bearing arrangement has an additional, axially central bearing sub-assembly. The bearing sub-assembly includes two half-shells which are axially fixed by way of guide surfaces, whereby one is radially supported on the switch pole sub-assembly and the other is radially supported on the supporting framework of the drive device.

  • Low -voltage power switch with a bearing arrangement for a switch shaft
    Publication number: 20040070473
    Abstract: The invention relates to a low-voltage power switch, wherein the drive device (16) is fixed by means of a supporting framework (17,19) and the associated switch shaft (8) is fixed, by means of two axially external bearing sub-assemblies, to the switch pole sub-assembly (1) In order to ensure that the fitting corresponds to a position based on separate examination of the drive device, the bearing arrangement has an additional, axially central bearing sub-assembly. Said bearing sub-assembly consists of two half-shells (25 and 26) which are axially fixed by means of guide surfaces (45 or 55,56,57 and 58), whereby one is radially supported on the switch pole sub-assembly (1) and the other is radially supported on the supporting framework (17,18) of the drive device (16).

  • Insertable and retractable switching device comprising a blocking bar which prevents wrong operation
    Patent number: 6252186
    Abstract: A switching device has a closing device and a traversing mechanism for insertion and retraction relative to an insertion frame, where the said devices can be operated only in the OFF state of the switching device. A blocking bar having a cam element that cooperates with a carrier of an OFF operator is guided by elongated holes behind an operator's console of the switching device. The carrier and the cam element work together in such a way that the OFF operator can be pulled inward when the blocking bar is operated, thus signaling to the user that the switching device is locked in the OFF state.
