Abstract
A drive, for a switching device including a contact system with a fixed and a moving contact, including an actuator for operating the moving contact for closing or opening the contact system, and also a mechanical transmission device arranged between the moving contact and the actuator. The transmission device includes a toggle joint mechanism formed by a folding lever, pivotable about a stationary bearing, and a coupling element, connected to the folding lever via a moving bearing. The toggle joint mechanism is pivotable between a first end position and a second end position. When the changeover is made from the first to the second end position or vice versa, a maximum extended position occurs. The coupling element holds the moving contact in that position which closes the contact system in the first end position and in that position in which the contact system is open in the second end position.
