ABSTRACT:
An interconnecting circuit for connecting a first d.c. source to a second d.c. source. The circuit includes a first conductive connection extending between one terminal of the first source and one terminal of the second source, the first conductive connection including a first pair of relay contacts and a second pair of relay contacts. A second conductive connection extends between a second terminal of the first source and a second terminal of the second source, the second conductive connection being free of relay contacts. A first polarity responsive circuit includes a first relay winding coupled across the first d.c. source for energizing the first relay winding whenever the first d.c. source is connected in a given polarity, the first pair of contacts being closed whenever the first relay winding is energized. A second polarity responsive circuit includes a second relay winding coupled across the second d.c. source for energizing the second relay winding whenever the second d.c. source is connected in the given polarity. The second pair of contacts are closed whenever said second relay winding is energized.
