ABSTRACT:
The invention relates to a magnetic actuating device containing a reference element and an adjusting element which is movably disposed between first and second end positions with respect to the reference element. The reference and/or adjusting elements contain a magnetizable material. A drive coil is provided for generating a magnetic field that moves the adjusting element from the first to the second end position. A mechanical clamping device is provided for producing mechanical forces that move the adjusting element from the second to the first end position. A fixing device is provided with a permanent magnet for generating a holding force fixing the adjusting element in the second end position with respect to the reference element. The fixing device contains a fixing unit separated from the adjusting element and provided with the permanent magnet.
