Circuit for progressive switching-over of a transistor T1 for controlling a contactor. A second transistor T2 operating as a current generator has its base linked to the drain of the transistor T1 so as, via the potential Ud of the drain, to control the supply of additional current to the feedback capacitor Cr via the transistor T2 in such a way as to progressively turn on the transistor T1 or to turn it off. <IMAGE>
