Automatic transfer switch is an electrical device that plays a crucial role in emergency power supply systems. It ensures the continuous power supply and reliability of the load circuit by monitoring the status of the power circuit in real-time and automatically performing switching operations. During the power conversion process, the automatic transfer switch can ensure continuous power supply to the load circuit, avoid power interruption, and thus improve the reliability and stability of power supply. It is widely used in places that require high reliability power supply, such as hospitals, banks, power plants, chemicals, metallurgy, airports, docks, office buildings, hotels, shopping malls, sports fields, military facilities, etc.

Conversion switch, also known as combination switch, is a switching device that plays an important role in circuits. The operation mode of the switching switch is usually a flat operation with left and right rotation, which is different from the up and down flat operation of the knife switch. By rotating the switch handle, the contacts will move from one position to another, thereby transmitting signals or power in the circuit to different paths.
