Control device of a direct-current electric motor for a windshield wiper

In a control device of a direct-current electric motor having an armature for driving a windshield wiper, comprising:

• a manually controlled switch for controlling the operation of said windshield wiper;
• a first terminal of the armature connected to ground;
• a second terminal of the armature connected to a power supply terminal through said manually controlled switch;
• a parking switch means for controlling the stopping of said motor in a fixed position corresponding to a parking position of said windshield wiper, wherein said parking switch means comprises an electric circuit having a plurality of contact means, said plurality of contact means being designed to interact with a track means, said track means having electrically conductive and insulating sectors;
• and
• means for ensuring relative rotary movement, controlled by said motor and taking place between said plurality of contact means and said track means;
• the control device being characterized in that the interaction of said plurality of contact means and said track means ensures that the power supply to the motor is maintained up to a desired fixed stopping position and that, when this stopping position is reached, the power supply to the motor is cut off and the motor armature is short-circuited, and wherein said plurality of contact means comprises a first contact connected to said manually controlled switch, a second contact connected to ground, and a third contact connected to said power supply terminal via an electrical breaker means, said electrical breaker means being designed to remain open when said motor is operated continuously and close when said manually controlled switch is actuated to stop said motor.
