摘要：
A locked state for a movable part (11) of switchgear is created by deflected spring wires (15) entering a recess (12). Said device is reversible and has the advantage of being safe since it is completely passive, and it improves the dynamics of the movement of the movable part in particular by damping impacts when entering the abutment state. The invention can be applied to the drive rod of a vacuum circuit-breaker.
