<p>PROBLEM TO BE SOLVED: To decrease the power supply cables to be concentrated at an ignition switch or a fuse box by distributing the functions for distributing, conducting and interrupting the power supply for the ignition switch, using multiplex communication and semiconductor switching elements. SOLUTION: A power supply interrupter 5 is disposed in the way of a feeder line from a battery power supply 1, and a feeder line is wired from the power supply interrupter 5. Furthermore, a power supply terminal 15 is disposed so that feeder line and power is fed therefrom to an electric load. Distribution of power supply and power supply to the electric load are controlled, using multiplex communication. When a switching element having self-protective function is employed for power supply, fuse function can be imparted to the switching element. Consequently, the number of fuses can be decreased, and the feeder wire as well as the control signal wire can be decreased.</p> |
