A disconnector (1) including a movable conductive unit (6) comprising a main electrically conductive body (9) has a main contact (4b) as well as an arcing contact (5b). According to the invention, the unit (6) further comprises a secondary body (14) mounted to move in sliding relatively to the main body (9) along a movement direction (11) of the unit (6), the secondary body (14) being designed to be connected to a connection point (22) of a drive device of the unit (6), the unit further comprising resilient return means (16) interposed between the bodies (9, 14), the switchgear being designed so that during an opening operation the resilient return means (16) can firstly store energy as a result of the secondary body (14) moving relative to the main body (9), and can then release the stored energy in order to cause the main body (9) to accelerate. |
