<p>PROBLEM TO BE SOLVED: To obtain a junction box, which is fitted with semiconductor relays, and supplies load power to loads which correspond to the kinds of cars, without having to use mechanical relays, even if countries differ or the kinds of card differ. SOLUTION: On making of an ignition switch 7, a computer unit 10 turns semiconductor relays 11a, 11b, and so on in an on-state according to a control table 10a for the semiconductor relays, and power is supplied to loads 2a, 2b, and so on. Consequently, changes in specifications can be dealt with, only by changing a semiconductor relay control table, even if the kinds and grades of cars and nations differ, and their specifications change respectively.</p> |
