Abstract: A support-assembly suitable for a micro-switch of a switching device, including bracket-support-means suitable for being connected, in a stationary position, to a frame portion of the switching-device, coupling-protrusion-component shaped for being provided at an end of an operating-shaft of the micro-switch and for movably engaging with the bracket-support-component. The coupling-protrusion-component and the bracket-support-component being configured for enabling a rotation of the operating-shaft around a rotation-axis and for preventing a movement of the operating-shaft transversely to the rotation-axis.

Abstract: A switchgear apparatus (1) comprising a switching unit (2) comprising one or more electric poles (21), a truck assembly (4), on which said switching unit is mounted, said truck assembly being movable with respect to a supporting frame (3), actuation means (5) for moving said truck assembly, said switching unit being reversibly movable between an insertion position (A), at which said switching unit is electrically connected to an electric line, and a withdrawal position (B), at which said switching unit is electrically disconnected from said electric line and an electro-mechanical signalling arrangement (6) that is mounted on said truck assembly, said electromechanical signalling arrangement interacting with said actuation means to provide electric signals indicative of the position of the switching unit at said insertion position (A), at said withdrawal position (B) or at an intermediate position (C) that is different from said insertion position and said withdrawal position.The electro-mechanical signalling arrangement comprises an auxiliary contact device (7) of the rotational type and a first and second signalling mechanism (8, 9) to actuate said auxiliary contact device.
