路。A circuit for detecting instantaneous power interruption, a non-lock switch, and a relay consisting of contacts and coils constitute a cut-off circuit. Power is supplied to the magnetic bubble memory device through the contacts, and the power supply voltage is at a specified level. When the voltage drops to below, the cutoff circuit stops supplying the drive current to the coil, restores the relay, cuts off the power supply to the magnetic bubble memory device, and no power is supplied unless the switch is turned on again. A cut-off circuit in the event of a momentary power interruption.
