摘要：PURPOSE:To aim at electronization in a circuit bearing the above caption as well as to improve its controllability, by installing a position detecting switch detecting both stop and rotation positions of a windshield wiper motor, and constituting it to control operation of the wiper motor in a way of controlling a semiconductor switch element according to the output. CONSTITUTION:A windshield wiper motor A connects its first driving terminal A1 to the side of an output terminal on one side of a battery E, and connects its second driving terminal A2 to the side of an output terminal on the other of the battery E via a transistor TrB as a semiconductor switch element. In the said motor A, there is provided with a position detecting switch A4 in addition, which detects the rotation position, while the said switch A4 should be set so as to be connected to the side of the output terminal on one side of the battery E at the motor stop position and to the side of the output terminal of the other at the rotation position, respectively. And, a second transistor TrC is connected to an interval between this switch A4 and the said terminal A2, and both these transistors TrB and TrC aforesaid are controlled by a control circuit D whereby operation of the wiper motor A is controlled.
