Abstract

A power supply control circuit includes: a power supply unit that outputs the DC voltage for the load operation; a first switch of which opening/closing is controlled by applying the DC voltage from the power supply unit; a second switch which is manually operated to switch over the power supply; and a control unit. The second switch achieves a first state when not manually operated, and achieves a second state when manually operated. The control unit closes the first switch, if the second switch is changed to the second state and thereafter changed to the first state, when the second switch is in the first state and the DC voltage output from the power supply unit is not less than a predetermined value.
