The core components of an automatic transfer switch include a controller, sensors, and actuators. The controller is responsible for detecting the status of the power circuit and issuing control signals based on the preset logic; Sensors are used to convert the state of the power circuit (such as voltage, current, frequency, etc.) into electrical signals and transmit them to the controller; The actuator performs power switching operations based on the instructions of the controller. In addition to the core part, the automatic transfer switch also includes components such as the switch body, connecting wires, positioning brackets, etc. These components work together to ensure the normal operation and reliable switching of the automatic transfer switch.

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.
