Product Introduction
The LFE series auxiliary switches are one of the supporting components for high-voltage complete sets of equipment. They are suitable for controlling the closing, opening, interlocking, and signal circuits of various high-voltage switch operating mechanisms, and can also be used as conversion or combination switches. Its large-capacity on-off capability effectively overcomes the shortcomings of other auxiliary switches, such as limited capacity and low contact life. The service life of the product is significantly extended, making it an effective alternative to other similar auxiliary switches.

Working principle
The LFE series auxiliary switch adopts an indirect drive structure. The rotation of the square shaft drives the CAM, and then the CAM pushes the switch push rod, causing the moving contact piece to move, thereby achieving connection or disconnection to control the electrical circuit.
Switch structure
The LFE series auxiliary switches are composed of multiple units with the same structure. The fixed contact pieces and moving contact pieces are made of high-quality brass with silver plating treatment. The contacts are made of silver-nickel alloy composite contacts, featuring large on-off capacity and long contact life. The insulating sheet is made of high-quality flame-retardant chemical fiber material, which is heat-resistant, has high strength and good insulation performance. The structure is reasonable and dust-proof. The external connection method of the auxiliary switch is crimping. The number of switch poles and the on-off Angle can be flexibly combined and configured according to customer needs, which can meet various different needs of users.
