特徴とする切替回路。 An isolation transformer connected to an AC power supply, a charging circuit connected to the output side of the isolation transformer to charge a rechargeable power supply, and a charging circuit connected to the output side of the isolation transformer to drive a load with the AC power supply when energized. A relay circuit is inserted in series between the output side of the isolation transformer and the relay circuit, which switches the power source for driving the load so that the load is driven by a rechargeable power source when the power is not energized. A switch element is closed for a predetermined period of time from the start of energization to the relay circuit until the end of the switching operation, and when the switch element is opened, current is passed from the output side of the isolation transformer to the relay circuit to maintain the relay circuit. and a constant current circuit that limits the current to a constant current.
