What is the structural principle of the conversion switch?

The contact system of the transfer switch is composed of several static contact seats embedded in the insulation shell and moving contacts in the movable bracket. The moving contact is a double break docking type contact bridge, which rotates to different positions along with the shaft attached with a handle to connect or disconnect the circuit. The positioning mechanism adopts a roller card ratchet structure, equipped with different limit pieces, which can obtain switches of different gears. The conversion switch is assembled from multiple layers of insulating shells, which can be arranged in a three-dimensional manner, reducing the installation area. The structure is simple, compact, and the operation is safe and reliable.

The conversion switch can be composed of switches with different connection methods according to the requirements of the circuit to adapt to the requirements of different circuits. In control and measurement systems, circuit conversion can be achieved by using a conversion switch. For example, the switching of power supply for electrical equipment, the forward and reverse switching of electric motors, and the switching of voltage and current in measurement circuits. Replacing the knife switch with a conversion switch not only simplifies the control or measurement circuit, but also avoids operational errors and reduces the number of components used.

The transfer switch is a development of the knife switch, and its difference is that the knife switch operates in a vertical plane motion, while the transfer switch rotates in a horizontal plane motion and can be made into a multi contact, multi gear switch.
