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.
