Abstract: A low voltage contact assembly including 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 coupled to/uncoupled from corresponding first fixed contacts by rotation around said rotation axis, the first couple of movable contacts including a first and a second movable contacts housed in the rotating support and each having a corresponding first and second elongated contact body with a contact end protruding from the rotating support, the first and second elongated contact bodies lying parallel to each other in a rotation plane substantially perpendicular to the rotation axis. The low voltage assembly further includes a pressure exerting device having a pressing bar operatively coupled to the first and second elongated contact body and transversally placed with respect to the rotation plane of the first and second elongated contact bodies, and a first and a second elastic elements positioned at opposite ends of the pressing bar, the pressing bar further including a first and a second operating surface each including a corresponding first and second pressing surface protruding from the pressing bar and respectively acting on the first and second elongated contact body.

Abstract: A low voltage switching device including: one or more electric poles having one or more movable contacts and corresponding fixed contacts adapted to be coupled to or uncoupled from each other, a movable contact assembly including the mobile contacts and a main supporting and operating shaft reversibly movable between a first contact position, at which the movable contacts and the fixed contacts are uncoupled, a second contact position, at which the movable contacts and the fixed contacts are coupled, and a third contact position, at which the movable contacts and the fixed contacts are coupled and kept pressed; an operating assembly including a handle mechanism having a handle adapted to be reversibly moved by a user or a motor operated actuator (MOE) between a first, open, position and a second, closed, position; a driving assembly operatively connected to the operating assembly and to the movable contact assembly and including a kinematic chain and at least a driving spring, the driving assembly reversibly moving the movable contact assembly following a movement of the operating assembly from the open position to the closed position, and vice-versa. In the low voltage switching device the driving assembly includes a latching mechanism which is operatively coupled to the operating assembly and to the movable contact assembly, the latching mechanism interacting with the movable contact assembly and latching it in the first contact position during a first phase of the movement of the operating assembly between the first, open, position and the second, closed position, then unlatching the movable contact assembly when the operating assembly is in an intermediate position between the first, open, position and the second, closed position, thereby allowing the quick passage of the movable contact assembly from the first contact position to the third contact position in which the movable contacts and the fixed contacts are coupled and kept pressed.

Abstract: A switching device for LV electric installations is disclosed which can include an outer casing and one or more electric poles. Each electric pole can include one or more mobile contacts and one or more fixed contacts adapted to be coupled or uncoupled. A mobile contact assembly is operatively coupled with the mobile contacts such that the mobile contacts move together with the mobile contact assembly. The mobile contact assembly is adapted to reversibly move between a first contact position, in which the movable contacts and the fixed contacts are coupled and a second contact position, in which the movable contacts and the fixed contacts are uncoupled. A mechanical control assembly is provided for operating said mobile contact assembly.
