FIELD: low-voltage switching device.
SUBSTANCE: invention is related to a low-voltage contact group for a low-voltage switching device, in particular for a low-voltage switch, in particular, the present invention relates to a low-voltage contact group with a double movable contact. A low-voltage contact group is proposed, containing a rotating support part having a housing configured to rotate around an axis of rotation and providing support for at least a first pair of movable contacts, which can be connected to the corresponding first fixed contacts and disconnected from them by rotating around said axis rotation, wherein said first pair of movable contacts comprises first and second movable contacts, which are located in the rotary support part, and which have, respectively, first and second elongated contact bodies with contact ends protruding from said rotary support part, wherein said first and the second elongate contact bodies are arranged parallel to each other in a rotation plane substantially perpendicular to said rotation axis. The low-voltage contact group also contains a pressure application device containing a clamping bar operatively connected to said first and second contact bodies and located in a transverse direction relative to said rotation plane of said first and second elongated contact bodies, and wherein the first and second elastic elements are located on opposite sides. the ends of said clamping bar, which also has first and second working surfaces comprising, respectively, first and second clamping surfaces protruding from said clamping bar and acting on said first and second elongated contact bodies, respectively.
EFFECT: providing a low-voltage contact group, which can compensate for the possible situation of non-coplanarity in the correspondence of the contact surfaces and which is characterized by reliability, ease of manufacture and competitive production costs.
