[0033] The second housing 3 includes a main body 9, a first cover plate 10, and a second cover plate 12. The second cavity 8 is provided with a first welding port, and the first cover plate 10 is disposed at the first welding port. The second cavity 8 is provided with a second welding port opposite to the first welding port, and the second cover plate 12 is disposed at the second welding port. The first cover plate 10 is inserted into the main body 9. The glue injection port 11 is disposed on the first cover plate 10. The second cover plate 12 is inserted into the main body 9.

The inlet surface 14 is inclined relative to the limiting surface 15. The main body 9 is provided with a corresponding locking groove for the locking block 13.

[0034] In this embodiment, the static conductive sheet 5 is placed into a mold for injection molding to form the first housing 2 and the second housing 3. The follower 1 is assembled and wires are welded. The operator completes the wire welding through the first and second welding ports. Multiple wire bundles are encapsulated in the wires and inserted into the first cover plate 10 and the second cover plate 12. The second cavity 8 is filled with waterproof glue through the glue injection port 11. When in use, the follower 1 rotates with the side support, and the moving contact 4 rotates to make the static conductive sheet 5 form different circuits to generate different voltages and output them. The side support status is judged based on the voltage signal. This is a mature technology. The glue injection port 11 can also be set on the second cover plate 12.
