Abstract
A control device for a movable contact relative to a fixed contact of a vacuum bottle of an electrical switching device. The control device includes a principal mechanism for disconnection and connection of the contacts, of the mechanical energy accumulation type. The control device further includes an auxiliary disconnection-assistance mechanism arranged such as to accumulate mechanical energy when the movable contact is moved towards the connection position and such as to restore the mechanical energy thus accumulated in such a manner as to exert an additional disconnection force in the form of an impact tending to move the movable contact from the connection position towards the disconnection position when the movable contact is immobilized in the connection position despite the action of the principal disconnection force.
