description The invention relates to an on-load tap changer for switching among different winding taps of a step transformer without interruption. According to the invention, the selector contact unit (7) and the switching means (16, 17) for switching the load without interruption are jointly actuated without using an intermediate energy accumulator, by means of a threaded spindle (5) which is rotated by a drive motor (2) during a switching operation.
