Abstract (en)
An indicating device of a dual-power automatic transfer switch comprises a first driving component connected to a first moving contact of a first power supply and a second driving component connected to a second moving contact of a second power supply. The indicating device comprises a mechanical indicating device and an electrical indicating device; and an indicating part acting on the mechanical indicating device and the electrical indicating device. The first driving component and the second driving component respectively drive the indicating part to move; the movement of the indicating part drives the mechanical indicating device to move to a position indicating where the first power supply is switched on, a position indicating where the second power supply is switched on and a position where both the first power supply and the second power supply are switched off; the movement of the indicating part correspondingly actuates the electrical indicating device to indicate the switch on signal of the first power supply, the switch on signal of the second power supply and the switch off signal of the first power supply and the second power supply. A dual-power automatic transfer switch comprises the indicating device.
