摘要

The drive assembly (10) for switching a motor (M) on and off comprises a transformer (T) with at least one primary winding (Tp) and at least one secondary winding (Ts). The transformer is arranged so that its secondary winding emits a lower voltage than the alternating voltage received at its input. To the at least one secondary winding a motor is connected. In series with the at least one primary winding, a switch (S) is accommodated, preferably a relay.
