Non-maintenance type high-voltage isolation switch galvanic circle assembly

A maintenance-free type high voltage insulating switch conductivity return circuit total program comprises a wiring board, a conduction shaft, a conduction tube, a sensing finger, and a right contactor. The utility model is characterized in that the wiring board is connected with the conduction shaft, the outside of an upper nylon case is inserted with a wiring base, a conduction belt is fixed on the conduction shaft through a bolt, the lower end of the conduction shaft is fixed on the wiring base through a lower nylon case, the conduction shaft can rotate in the upper and the lower nylon cases, the wiring base is connected with the conduction tube, the conduction belt, the conduction shaft, and a main body for fixing the upper and the lower nylon cases, the conduction belt and the conduction shaft can rotate in a hollow cavity of the wiring base, and the conduction tube can be connected with the wiring base which is installed on an insulator. The utility model has the advantages of strong conduction performa
