Abstract
A power supply control device includes a control unit that executes determination processing that, when an operation instruction is received from a switch input detection unit, determines, in a case in which the switch circuit is turned on, whether or not a power source voltage value will decrease to or below an acceptable voltage value on the basis of a power source voltage value obtained from a voltage detection unit and a load current value stored in a storage unit in advance; and in the determination processing, executes switch control processing which allows the switch circuit to be turned on if the power source voltage value is determined to not decrease to or below the acceptable voltage value and does not allow the switch circuit to be turned on if the power source voltage value is determined to decrease to or below the acceptable voltage value.
