Abstract
An electric system for use in a motor vehicle. The system includes a battery mounted in the vehicle body; a controlling device mounted in the vehicle body and having first and second switches; and a positive/negative switching device mounted in the vehicle body and electrically connected to the battery and the controlling device. The switching device has an output member which includes first and second output parts. The switching device assumes, when the first switch of the controlling device is turned ON, a first condition wherein the first and second output parts are charged positive and negative respectively, and assumes, when the second switch of the controlling device is turned ON, a second condition wherein the first and second output parts are charged negative and positive respectively. First and second electric devices are mounted in the door and have an input member which includes first and second input parts. The first electric device is energized only when the first and second input parts are charged positive and negative respectively, and the second electric device is energized only when the first and second input parts are charged negative and positive respectively. The feeding system further comprises a member for electrically connecting the first and second output parts to the first and second input parts.
