Transfer switches have advantages such as multiple contacts, multiple positions, small size, reliable performance, convenient operation, and flexible installation. The use of conversion switches can simplify control or measurement circuits, avoid operational errors, and reduce the number of components used. A conversion switch is a switching device that plays a crucial role in a circuit. It achieves circuit switching and control through the combination and rotation of multiple contacts. It is widely used in machine tool electrical control, motor control, and measurement systems.

The conversion switch is often used as an introduction switch for power supply in the electrical control circuit of machine tools, playing a role in isolating the power supply. It can also serve as a control switch for directly controlling the infrequent start and stop of small capacity asynchronous motors. In control and measurement systems, conversion switches can be used for circuit conversion, such as the switching of power supply for electrical equipment, the forward and reverse switching of motors, and the conversion of voltage and current in measurement circuits.
