装置。 In a device that outputs a switching signal to a magnetic contactor via an output circuit connected to a sequence power supply in response to a switching command from a control device connected to a control power supply, and switches the power supply between an inverter device and a bypass power supply. The electromagnetic contactor is of a mechanical latch type, and the sequence power supply is provided with a power loss detection circuit that outputs a switching command to the output circuit when the power supply is lost, and furthermore, a capacitor is provided at the front stage of the output circuit, and a capacitor discharges from the capacitor. What is claimed is: 1. A switching device for an uninterruptible power supply, comprising: a reverse current blocking diode.
