<p>A power source, esp. for a motor vehicle supplies at least two loads through cables and switches. Series circuits consisting of the load (1) and switch (3) are connected in parallel to the supply cables (7) and the switches are connected in parallel to at least one control wire (19) connected to a control unit (15). The latter has a coder for the switches (3) controlled through operating switches (17) and/or control switches. When a switch (17) is operated, the coder delivers to the corresp. switch (3) a selectively allocated series code signal to which decoders in the switches (3) respond.</p> |
