ABSTRACT A moving element is held without contacts in a relatively stable holding position, out of which it is released by the application of an external force. The relatively stable holding position is obtained by superimposing a potential field of magnet edges by a further potential field based on a mechanical bias of the moving element or a magnet in such a manner that the curve of the total potential has a trough corresponding to the holding position. By applying an external force, the moving element is moved to a peak position of the total potential curve, whence it is subject to accelerating forces. A typical embodiment, characterized by rare earth magnets, is particularly suitable for printers for initially accelerating moving coil operated print hammers. GE9-78-023
