Abstract

1. Mechanism for rapid manual closing of a current breaking device, notably a switch or circuit breaker, having a handle (10) connected by a kinematic chain to a contact arm (32), characterized in that elastic part (56) forming an abutment which can be overrun, is located at a predetermined point on the trajectory of movement of one (54) of the elements of the switchgear closing mechanism in such a way as to impede said movement and to constitue a hangup point (alpha2 ) requiring an increased force on the handle to overrun said point 'alpha2 ) corresponding to a position of the contact arm (32) close to the position where the contacts (38, 40) come into contact, said part (56) being inactive after said overrun, to bring about rapid closing by the action of said increased force and when the handle (10) is moved in the switchgear opening direction.
