This control device comprises an amplifier consisting of a transistor associated with a relay, a capacitor inserted in the emitter-base circuit of said transistor and a potentiometer for adjusting the charging time of said capacitor, and switch means for associating said amplifier to a fixed-stop system of a wiper motor, said transistor being held in its saturated condition during the charging time, the input and output of said amplifier being put at the same potential immediately as the motor is started by the action of said fixed-stop system, thus causing the discharge of said capacitor so as to block said transistor and deenergize said relay.
