The SWQ2 dual-power automatic transfer switch produced by Zhejiang Siwei Electrical Technology Co., Ltd., as its name implies, is composed of electrical appliances with one or more transfer switches and other necessary electrical appliances. "Power switch" and dual power automatic transfer switch belong to the same product. The dual-power automatic transfer switch can automatically judge the quality of the two power supplies. If the common power supply loses power, the dual-power automatic transfer switch will immediately automatically switch to the standby power supply, so that the load can be supplied normally.

The structure of the SWQ2 dual-power automatic transfer switch is mainly composed of a controller, a conversion mechanism, and the body; the controller is very important. It can be said that the controller is the brain of the dual-power automatic transfer switch. It can control the dual-power automatic transfer switch to perform the two-way power supply. Conversion: The conversion mechanism is composed of a driving mechanism and a transmission mechanism; its function is to realize continuous disconnection and connection, and it can also determine the mechanical reliability of the dual power automatic transfer switch; the body part is composed of contacts and contacts The composition of the mechanism and the arc extinguishing chamber; directly determines the electrical characteristics of the dual power automatic transfer switch.

The SWQ series of dual power automatic transfer switches are used in a wide range of applications, such as elevators, industrial and mining, banks, and hospitals where power can be cut off. There are usually dual power automatic transfer switches, because once the power is cut off, it will cause huge economic losses and even Will threaten the safety of human life.
