China Factory Super Long Electric ATS Change-Over Switch 16-3200A Automatic Transfer Switch

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.

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.

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.

A switching switch is a type of electrical device that can be used for switching between two or more power sources or loads. It can switch circuits by operation, switching them from one set of connections to another. Mainly used for infrequently connecting and disconnecting circuits, connecting power and loads, measuring three-phase voltage, and controlling the forward and reverse rotation and star delta starting of small capacity asynchronous motors.
