Universal transfer switch principle

The principle of the universal transfer switch is mainly to control the circuit by changing the connection mode of the contact, and then realize the control of the equipment.

When the handle of the universal transfer switch is operated to different gears, the contact is closed or disconnected through the mechanical transmission mechanism such as the rotating shaft and CAM to achieve different control functions. This switch usually has multiple gears, which can be used to control the speed regulation, starting and reversing of the motor, as well as the conversion and measurement of the circuit, etc. The structure of the universal switch generally includes a handle, a rotating shaft, a CAM, a contact seat and a positioning mechanism.
