Described herein is 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 said movable contacts and a main supporting and operating shaft reversibly movable between a first contact position, at which said movable contacts and said fixed contacts are uncoupled, a second contact position, at which said movable contacts and said fixed contacts are coupled, and a third contact position, at which said movable contacts and said 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; and a driving assembly operatively connected to said operating assembly.

The invention relates to a self-supported activation device for an electromechanical switch, which can be used for the isolation of a faulty element of a battery, comprising a set of electrically connected elements. The activation device (1) is intended to activate switching in a switching device (2) of the type having electrical contact means (3) that can move between first and second electrical positions. The activation device comprises a current sensor (6a, 6b), a retaining element (7), and at least two movable elements (8, 9) solidly connected to a coil (10). When a current is detected by the current sensor (6a, 6b) the activation device can move from a non-activation configuration, in which the movable elements are retained by the retaining element in a first position intended to prevent the movement of the contact means of a switching device, into an activation configuration, in which the movable elements are no longer retained in the first position by the retaining element and instead occupy a second position intended to allow the movement of the contact means of a switching device. The coil (10) comprises a passage space for at least part of the contact means, and each of the movable elements can rotate about an axis such as to clear the passage space, in the aforementioned second position, while remaining solidly connected to the coil.
