Title: POWER SUPPLY CONTROL DEVICE
Abstract:
Disclosed is a power supply control device that is provided with: a semiconductor latch circuit that maintains, in a state wherein power is not supplied, a first state wherein power supply to a load is interrupted or a second state wherein the load is supplied with power; a drive circuit that shifts the state of the semiconductor latch circuit to the second state from the first state in the cases where a magnetic force is detected in a state wherein power is supplied; and a magnetically sensitive switch, which supplies the drive circuit with power in the cases where the magnetic force is applied, and which interrupts the power supply to the drive circuit in the cases where the magnetic force is not applied.
