<p>The unit has a drive (10) for operation of a power switch (24), and a position detector for detecting ON-position of the power switch. The drive activates the position detector by a mechanical gear. The gear has a spring unit, which is arranged in a movement transmission path between the drive and the position detector in such a manner that the spring unit receives an elastic deformation during closing of the power switch. The spring unit is designed as a helical spring (32), a torsion rod and an elastically deformable lever.</p> |
