According to the invention, actuating the start-stop switch 7, coupled to a potentiometer for adjusting a variable resistor R10 for discharging a capacitor C3 linked to a cut-off transistor T4 for the supply to a bistable flip-flop T1, T2, 4, 5 makes it possible to control the continuous or intermittent operation, with adjustable delay for the stopping of the blade of the windscreen wiper system, at its rest or fixed stop position. The state changes of the bistable flip-flop T1, T2, 4, 5 control the polarity inversions for the reversible DC electric motor 1 which drives the blade. Usable for equipping motor vehicles. <IMAGE>
