The automatic transfer switch can quickly switch to a backup power source in the event of a power failure, ensuring continuous power supply to the load circuit. Through the built-in controller and sensors, the automatic switching switch can monitor the status of the power circuit in real time and automatically perform switching operations according to preset logic. The automatic transfer switch has multiple models and specifications to choose from, to meet the needs of different places and loads. The automatic transfer switch emphasizes safety in the design and manufacturing process, which can ensure the safety of operators and the stable operation of equipment.

The conversion switch is composed of a combination of multiple contacts, which are fastened as a whole by bolts. The contact system consists of several static contact seats embedded in the insulating shell and dynamic contacts in movable brackets. The moving contact is a double breakpoint docking type contact bridge, which rotates to different positions on the rotating shaft with a handle to connect or disconnect the circuit. The positioning mechanism adopts a roller card ratchet structure and is equipped with different limit components to obtain switches for different gear positions. The conversion switch is assembled from a multi-layer insulated shell and can be arranged in a three-dimensional manner, reducing the installation area. The structure is simple and compact, and the operation is safe and reliable.
