Product Introduction
The transfer switch is used for manually and infrequently connecting and disconnecting circuits for control or conversion purposes. It can also be used as a circuit control switch, test equipment switch, or master control switch. It is widely applied in industries such as power, industrial automation, and process automation. Its large-capacity on-off capability effectively overcomes the shortcomings of other transfer switches, such as limited capacity and low contact life, significantly extending the product's service life. It is an effective alternative to other similar changeover switches.

Working principle
The LZB series transfer switch adopts a manually driven structure. By manually rotating the handle, the square shaft rotates to drive the CAM, and then the CAM pushes the switch connecting rod, causing the moving contact piece to move, thereby achieving connection or disconnection to control the electrical circuit. The positioning mechanism serves the functions of positioning and resetting.
Switch structure
The LZB series changeover switches feature flexible switching operations, compact structure, and high safety and reliability. It adopts a multi-position design, with the positioning type capable of controlling up to 12 positions. The number of switch poles and the on-off Angle can be flexibly combined. The fixed contact piece and the moving contact piece are made of high-quality brass, and the contacts are made of silver-nickel alloy composite contacts, featuring a large on-off capacity and a long contact life. The insulating sheet is made of high-quality flame-retardant chemical fiber material, which is heat-resistant, has high strength, good insulation performance, and a reasonable structure to prevent dust. It can be well used in various electrical equipment.
