ABSTRACT:
A set of battery jumper cables includes a pair of single pole, single throw switches, or equivalent semiconductor implement switches. The switches are connected in series between the battery connection terminals of each cable in the set to prevent arcing. Control wires and a delay circuit connect the two terminals at one end of the set to the operating coil of one of the single pole switches. Similarly, another set of control wires and a delay circuit connect the terminals at the other end of the set to the operating coil of the other switch. In operation, these two switches in their unenergized state are open and automatically current flow through the cable set until after all four cable terminals are connected respectively to battery terminals and the relay delay has timed out, thus preventing arcing as the terminals are connected and disconnected or if the terminals at one end are shorted to each other. A pair of double pole, double throw, relay coil operated switches, or equivalent semiconductor implemented switches, automatically match the polarity of the battery terminals interconnected by the jumper cables. Because of the delay in closing the single pole switches, these double pole switches establish a proper polarity match before the single pole switches close.
