Low voltage contact assembly

A low voltage contact assembly comprising a rotating support having a body adapted to rotate around a rotation axis and supporting at least a first couple of movable contacts that can be couple to/uncoupled from corresponding first fixed contacts by rotation around said rotation axis, said first couple of movable contacts comprising a first and a second movable contacts housed in said rotating support and each having a corresponding first and second elongated contact body with a contact end protruding from said rotating support, said first and second elongated contact bodies lying parallel to each other in a rotation plane substantially perpendicular to said rotation axis, said low voltage assembly comprising a pressure exerting device having a pressing bar operatively coupled to said first and second elongated contact body and transversally placed with respect to said rotation plane of said first and second elongated contact bodies, and a first and a second elastic elements positioned at opposite ends of said pressing bar, said pressing bar comprising a first and a second operating surface each comprising a corresponding first and second pressing surface protruding from said pressing bar and respectively acting on said first and second elongated contact body, wherein said first and second pressing surface are cam-shaped surfaces symmetrically protruding from said pressing bar and wherein said first and second elastic elements each have a first end fixed on said rotating support and a second end acting on said pressing bar.
