摘要： A power switching device includes a switching relay for supplying power to a main circuit by switching between power from a main power supply and power from a supplementary power supply, and a control unit for controlling the switching relay. The control unit includes a voltage detecting unit for detecting a voltage value of the power supplied by either the main power supply or the supplementary power supply. The power switching device includes a first switch assisting unit, composed of semiconductor switching elements, for feeding the power from the main power supply to the main circuit when the voltage detecting unit detects that the voltage value of the power is above a predetermined value, and a second switch assisting unit, composed of semiconductor switching elements, for feeding the power from the supplementary power supply to the main circuit when the voltage detecting unit detects that the voltage value of the power is below the predetermined value. The power switching device performs an effective instantaneous remedial step for a power interruption, without the need for a capacitor.
