Abstract
An actuating device for a vacuum switching tube has a connecting element which can be connected to an electric contact of the vacuum switching tube, an electromagnetic actuating device for displacing the connecting element between a first and a second position, and a retaining yoke, relative to which the connecting element can be displaced and has a first magnetic element. The first magnetic element generates a first and a second magnetic circuit in the retaining yoke. The actuating device further has a ferromagnetic retaining anchor, which is arranged on the connecting element. The retaining anchor is located in the first position of the connecting element in the first magnetic circuit and in the second position of the connecting element in the second magnetic circuit. The connecting element is held in the first and in the second position by a respective magnetic force between the retaining yoke and the retaining anchor.
