<p>An insertion-extraction-mechanism (1) for inserting/extracting a switching-device (2) in/from a switchgear (3), comprises: - displacing-means (4, 14) configured for exerting on the switching-device (2) a force (5) so as to move in a first direction (6) movable contacts (7) of the switching-device (2) with respect to stationary contacts (8) of the switchgear (3), and - driving-lever-means (9) configured for operating, through an external-driving-force (12) the displacing-means (4, 14). The driving-lever-means (9) are further configured for exerting on the switching-device (2), upon an external-motion-force (13), a respective force (10) so as to move in a second direction (11), opposite the first direction (6), the movable contacts (7) with respect to the stationary contacts (8).</p> |
