[0040] Working principle: When using this high stability and reliability isolating switch, first, refer to Figures 1 to 5 , insert the wiring harness 3 into the interior of the wiring port 2, so that the movement of the wiring harness 3 will push the moving plate 4 to slide on the fixed rod 5, and then the movement of the moving plate 4 will squeeze the first spring 6, and then the first spring 6 will be compressed, and the movement of the moving plate 4 will pull the first pull rope 7 to move, and the rotation of the rotating rod 9 drives the gear 11 to rotate, so that the rotation of the gear 11 drives the push rod 12 to move, and then the gas inside the gas storage rod 13 is squeezed by the push rod 12 and transported to the inside of the air pipe 14, so that the air in the air pipe 14 is transported to the inside of the sealing ring 15, and then the inside of the sealing ring 15 is filled with air and expanded, and then the sealing ring 15 can fit the outer wall of the wiring harness 3, so that the gap between the wiring harness 3 and the wiring port 2 can be sealed, thereby preventing the entry of dust and impurities, and thereby achieving the purpose of high stability and reliability;

[0041] refer to Figures 1 to 5After the wiring harness 3 is released from the squeezing of the shift plate 4, the shift plate 4 can be pushed back to its original position by the first spring 6, and the rotating rod 9 will also drive the push rod 12 to reset through the gear 11, thereby causing the push rod 12 to move and generate negative pressure inside the gas storage rod 13. Then, the negative pressure inside the gas storage rod 13 will re-absorb the gas into the gas storage rod 13 through the air pipe 14 for storage, thereby reducing the friction between the movement of the wiring harness 3 and the sealing ring 15, thereby protecting the sealing ring 15.

[0042] refer to Figures 1 to 3 and Figure 6 When installing the wiring harness 3, it is only necessary to insert the wiring harness 3 into the interior of the wiring port 2, and then the movement of the wiring harness 3 will squeeze the protrusion 16, and the movement of the protrusion 16 will squeeze the third spring 17.
