Abstract: A switch pole for a low voltage switching device includes an insulating casing that defines an internal space having a contact region and an arc extinguishing region. The switch pole further includes a first pole terminal and a second pole terminal, each connectable to corresponding line conductors of an electric line. A fixed contact assembly and a movable contact assembly are arranged in the contact region and include fixed contacts and movable contacts that can be selectively coupled or uncoupled. The movable contact assembly includes an insulating cover that at least partially covers one or more conductive portions of the movable contact assembly. The insulating cover is hinged to a supporting structure of the movable contact assembly so as to move together with the supporting structure and to reversibly move relative to the supporting structure when the movable contact assembly rotates about a rotation axis during switching operation.

Abstract: The present invention relates to a single-pole or multi-pole switch to be used preferably in low-voltage systems. The switch (1) comprises an outer casing (2) containing for each pole at least one fixed contact (10) and one mobile contact (20) which can be reciprocally coupled to/uncoupled from each other. The mobile contacts (20) are housed in suitable seats (25) provided on a mobile element (50). The switch (1) according to the invention is provided with a control mechanism (60, 61) comprising mechanical means supported by a structural part (70). This control mechanism (60, 61) is connected to the mobile element (50) through first removable connection means (64) and to the outer casing (2) through second removable connection means (65). The switch (1) also comprises means to support the mobile element (50) which are connected to the structural part (70) of the control mechanism (60, 61) through third removable connection means (66).
