ABSTRACT:
Battery current is drawn by a motor vehicle electric motor speed controller through an electronic switch. The load current carrying circuit of the switch is made conductive to permit battery current to be drawn by the controller when a motor speed command signal indicates a non-zero desired motor speed, and nonconductive to prevent substantial battery current from being drawn by the controller when the motor speed command indicates a desired motor speed of zero.
