Windshield wiper motor circuit

A windshield wiper circuit arrangement comprising:

• an electric drive motor which is reversible with respect to the direction of rotation;
• a voltage source having first and second terminals each of a different polarity;
• a reversing switch interposed between said motor and said voltage source and having a first changeover bridging contact in cooperative switching relationship with a first pair of stationary contacts, and a second changeover bridging contact in cooperative switching relationship with a second pair of stationary contacts, said bridging contacts being carried by and simultaneously operable by a relay;
• limit switch means for characterizing first and second rotational end positions of said motor;
• and store means for controlling said relay, and for storing a representation of the switching state of said relay in at least one of said end positions, said store having a set input and a reset input;
• said limit switch means alternately connecting one of said first pair of stationary contacts to said first and second terminals and concurrently alternately connecting one of said second pair of stationary contacts to said second and first terminals;
• said set input and said reset input receiving control signals from said limit switch when said limit switch indicates said first or second position;
• the other of said stationary contacts being connected to the same terminal of said voltage source.
