    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.

    Abstract: A connecting-device for a switchgear apparatus, includes: tulip-cluster-portions for electrically engaging with a contact-stud-element; a mounting-end-part for the mechanical connection to a pole-terminal, and conductive-transmitting-portions for transmitting electrical current from the contact-stud-element to the pole-terminal, each of the conductive-transmitting-portions extending from the respective tulip-cluster-portion to a respective base-portion of the mounting-end-part. The tulip-cluster-portions with the respective conductive-transmitting-portions and with the respective base-portions are integral with one other so as to define respective single-piece-portions.
