Abstract

The invention relates to a manual drive for step-by-step operation, without any power, of a tap changer (1) on a tap-changing transformer. The manual drive has a position indication wheel (4) which is used not only, in conjunction with a pointer (15), for actual position indication, but at the same time as a component of mechanical final-position limiting (10, 11, 12). It can also furthermore be used (18) in a particularly advantageous manner as a component of electrical switching monitoring.
