[0026] Please see Figure 1-6A pneumatic valve control switch indicator structure includes a switch body 1, a valve stem 2 disposed on the inner side of the switch body 1, a support housing 3 disposed on the lower inner surface of the switch body 1, an air inlet 4 disposed on the lower surface of the support housing 3, an air outlet 5 disposed on the outer surface of the support housing 3, a push plate 6 fixed on the lower surface of the valve stem 2, a first sliding conductive rod 7 and a second sliding conductive rod 8 respectively fixedly connected to the upper surface of the push plate 6, and a first fixed connecting rod 9 disposed on one side of the switch body 1. The inner end of the switch body 1 is fixed with a first U-shaped contact plate 10. The other side of the switch body 1 is provided with a second fixed contact rod 11. The inner end of the second fixed contact rod 11 is fixed with a second U-shaped contact plate 12. The outer end of the second fixed contact rod 11 is fixed with a contact base 13. Multiple sets of light-emitting diodes 14 are fixedly connected to the outer surface of the contact base 13. By adopting the contact base interconnection structure, the contact base is provided with multiple contact holes, which facilitates the insertion of light-emitting diodes for power connection. It is easy to install, easy to disassemble, and easy to maintain and replace when damaged.

[0027] The outer surface of the power connector 13 is provided with power connector holes 130, and multiple sets of power connector holes 130 are evenly distributed on the outer surface of the power connector 13; this facilitates the insertion and installation of light-emitting diodes 14, making installation and replacement convenient.

[0028] The first sliding conductive rod 7, the second sliding conductive rod 8, and the push plate 6 are made of brass; this facilitates electrical connection and conduction.

[0029] The upper surfaces of the first sliding conductive rod 7 and the second sliding conductive rod 8 are provided with ball-head protrusions, which press against the outer surfaces of the first U-shaped contact plate 10 and the second U-shaped contact plate 12 respectively; this facilitates touching and pressing the U-shaped contact plate, making it easy to connect to electricity.

[0030] The first fixed contact rod 9 and the first U-shaped contact plate 10 are made of brass. The first fixed contact rod 9 protrudes outward from the switch box 1, and the outer end of the first fixed contact rod 9 is provided with a threaded mounting protrusion 90; it is convenient to install circuit wires; the upper surface of the support housing 3 is provided with a sliding hole, and the outer surfaces of the first sliding conductive rod 7 and the second sliding conductive rod 8 are slidably connected to the inner surface of the sliding hole of the support housing 3; the outer surface of the push plate 6 is slidably attached to the inner surface of the support housing 3.

[0031] In use, a valve stem 2 is provided on the inner side of the switch body 1. A support housing 3 is provided on the lower inner surface of the switch body 1. An air inlet 4 is provided on the lower surface of the support housing 3, and an air outlet 5 is provided on the outer surface of the support housing 3. A push plate 6 is fixed on the lower surface of the valve stem 2. A first sliding conductive rod 7 and a second sliding conductive rod 8 are fixedly connected to the upper surface of the push plate 6. In use, air is introduced through the air inlet 4, which can push the push plate 6 upward, causing the valve stem 2 to rise, which in turn causes the first sliding conductive rod 7 and the second sliding conductive rod 8 to rise.

When the valve rod 2 rises, the circuit can be connected, and its light-emitting diode 14 lights up, which can detect whether it is open. When the airflow is closed, the valve rod 2 descends due to its own weight, which drives the first sliding conductive rod 7 and the second sliding conductive rod 8 to descend and move, separating from the first U-shaped contact plate 10 and the second U-shaped contact plate 12, which can close the circuit, and the light-emitting diode 14 turns off.

[0032] Furthermore, the outer surface of the power connector 13 is provided with power connector holes 130, and multiple sets of power connector holes 130 are evenly distributed on the outer surface of the power connector 13; this facilitates the insertion and installation of light-emitting diodes 14, which are easy to install and replace; they can be directly plugged in for installation and simply pulled out for disassembly.
