It is usually used to ensure that the system can quickly switch to the backup power supply when the main power supply fails or is unstable.

[0003] Application number: CN201920577120.6, discloses a dual power automatic transfer switch, which can send out a signal and sound an alarm at the first time of a circuit breaker through the setting of a circuit breaker alarm system. The setting of the rotating rod can rotate along with the automatic transfer switch, and the rotating rod can trigger the alarm system and the normal indication switch. The setting of the normal power indicator light can intuitively display the working status of the dual power automatic transfer switch to ensure power supply safety. When the automatic transfer switch switches to the backup power supply, the rotating rod will trigger the alarm button, the alarm will sound, and the signal transmitter will send a circuit breaker signal to the responsible personnel to notify the unexpected situation, so that the responsible personnel can check it in time.
