The existing switch panel products often have problems with complex assembly structure and tightly bound connection structure in structural design. That is, the switch component and the back shell are generally tightly bound and assembled together, which makes it inconvenient to disassemble and assemble the two. Once a failure or damage occurs, the maintenance process is not only costly but also time-consuming.

[0003] In addition, with the development of science and technology, more and more devices in life require a switch panel to turn on and off, which will also lead to more and more switch panels. The existing switch panels have a single style and function, and the original switch panels cannot be updated and upgraded according to actual needs. In order to match a device with multiple auxiliary functions, a corresponding new switch panel needs to be designed and produced.
