Abstract
PURPOSE: To change an electric load with an command switch with an ignition switch OFF and to stop the supply of power with the command switch not applied, by providing the command switch and a power supply control circuit and also input means.
CONSTITUTION: With an ignition switch 2 OFF, since no power supply is given to a central multiplex processing computer 3, switch terminal computer 4, and meter terminal computer 6, the total current consumption for all the computer and its associated units 3, 4, 6 can be kept zero. Further, when any one of the command switches 10a, 10b, 10c for load driving command signal production is ON, a current flows to a coil 14a, of a relay 14 with a logical sum circuit for diodes 15a, 15b, 15c to close the contact b. Thus, multi-processing computers 3, 4, 6 can be operated. Accordingly, this unit can effectively be used to the multiplex processing computer system of automobiles in which a minimized current is requested at car parking and instantaneous operation is demanded at the operation of command switches.
