PURPOSE:To give the holding function to a power switch which has not a holding mechanism, by providing a storage circuit for a logic circuit which controls the second control circuit which controls a load in accordance with the power switch and the state of the first control circuit. CONSTITUTION:A power supply control circuit 100 which controls the power from a power source 1 to a load 7 includes the second control circuit 6, which controls directly the power, and a logic circuit 5 which takes in the state of the first control circuit including an ignition key through a detecting part 3 as the input and controls the second control circuit 6 in accordance with this input and the state of a power switch 4. Since the state of the power switch 4 having no holding mechanisms is stored in a storage circuit 8, the operation of the power switch is not affected even if the state of the first control circuit is changed. |
