[0023] Compared with the prior art, the beneficial effects obtained by the technical solution of the present invention are:

[0024] 1. The present invention can implement 86-type panel switches with different functions and forms according to different requirements, with flexible assembly, making the functions diverse. During the production process, the manufacturer only needs the same mold to produce the back shell, rear fixing frame, isolation component, and button protection board in different forms of the 86-type panel switch of the present invention, greatly reducing the production cost and labor cost. Moreover, due to the same accessories, it is beneficial for subsequent maintenance or replacement of the panel form, etc.

[0025] 2. The button protection board covers the chip board, and there are switch through holes on the button protection board corresponding to 4 groups of micro switches for the 8-key type and 3 groups of micro switches for the 6-key type. Three groups of switch through holes symmetrically arranged on the first set of parallel sides correspond to 3 groups of micro switches for the 6-key type on the chip board, and four groups of switch through holes symmetrically arranged on the second set of parallel sides correspond to 4 groups of micro switches for the 8-key type on the chip board. Therefore, as long as the button protection board is rotated so that different switch through holes correspond to different forms of chip boards, 86-type panel switches with 4 groups of button modules for the 8-key type and 86-type panel switches with 3 groups of button modules for the 6-key type can be realized.

[0026] 3. The bottom of the button protection board is provided with a first folding groove and a second folding groove for reservation of breaking. The first folding groove is located at 1 / 3 of the first set of parallel sides, and the second folding groove is located at 1 / 2 of the second set of parallel sides. In this way, after the button protection board is broken at the first folding groove or the second folding groove, a 2 / 3 button protection board or a 1 / 2 button protection board is formed. A touch panel can be set at the blank part after breaking, and a button component can be set at the button protection board part, thus realizing two combination forms of different touch panels and different button components.

[0027] 4. The present invention can also realize other forms of 86-type panel switches. For example, two groups of button modules in 4 groups of button modules for the 8-key type are combined into one, so as to realize 86-type panel switches with 2 groups of button modules for the 8-key type.

[0028] 5. Four positioning through holes are formed by the cooperation between the rear fixing frame and the back shell. Four elastic positioning columns are provided at the bottom of the isolation board, and the elastic positioning columns are inserted into the positioning through holes, so that the isolation component can be horizontally or vertically installed on the strong electric circuit board component, thus realizing the horizontal arrangement and vertical arrangement of the 86-type panel switch.

[0029] 6. The lower part of the elastic positioning column is a guiding part with an inclined surface, and the upper part of the elastic positioning column is a clamping part with a small angle with the horizontal plane. A protrusion is formed at the connection between the clamping part and the guiding part. The positioning through hole is in a quasi-rectangular structure, and the guiding part is arranged outward. The rear fixing frame is made of a metal structure. When placed horizontally or vertically, the inclined guiding part and the clamping part of the elastic positioning column always face the rear fixing frame and contact with the metal edge of the rear fixing frame, making the structure more stable and firm, and the disassembly and assembly smoother without jamming.

[0030] 7. In the present invention, a snap connection structure is adopted between the high-voltage circuit board and the rear case, and between the rear case and the rear fixing frame, so that the entire high-voltage circuit board assembly can be assembled directly by snap connection; a snap connection structure is adopted between the isolation assembly and the high-voltage circuit board assembly, and between the button assembly and the isolation assembly, so that the entire product can be assembled by snap connection, without the need for screwing with bolts, and disassembly and maintenance are also relatively convenient.
