Abstract
A drive for a switching device having a contact system with a fixed contact and a moving contact, includes a force initiation element for initiating a drive force, an actuator for actuating the moving contact to close or open the contact system and a transmission disposed between the force initiation element and the actuator. The transmission allows both transferring the contact system from the closed to the open state and transferring the contact system from the open to the closed state to be triggered by a drive force in the same direction, making the drive cost-effective and compact.
