[0003] The switch panel in prior art usually includes a base part embedded in the wall surface, an outer frame part manually detachable from the base part, and a function part limited by the base part. The outer frame part usually needs to be manually extruded to release the mechanical buckling between the outer frame part and the base part. In general, this mechanical buckling is achieved by extrusion or interference of injection molding or any stamping structure. Therefore, an opening can be designed on the outer edge of the outer frame part, which is used to pry open the outer frame part with a screwdriver or any tool to release at least part of the buckling mechanism, and expose the gap to facilitate manual prying of the outer frame part for disassembly, as described in the switch panel of the background art of Chinese utility model patent No. ZL201820868053.9. The base part is used to position the entire panel in the wall surface, for example, the installation of the bottom box is fastened in the wall surface by penetrating the screw in the installation hole. The central opening of the base part is used to accommodate and fix the function part, and the edge of the function part has a flange structure to stop the function part on the base part, and can be limited by fixed methods such as screw fastening.
