The top of the first cover is provided with a first button, a second button, a third button, a fourth button, and a fifth button sequentially from front to rear. The top of the second cover is provided with a sixth button, a seventh button, an eighth button, a ninth button, a tenth button, and an eleventh button sequentially from front to rear. A first circuit board is mounted on the bottom of the first cover, a second circuit board is mounted on the bottom of the second cover, and a limit post is mounted on the bottom of the middle seat.

[0007] As a further technical solution of this utility model, the first button, the second button, the third button, the fourth button and the fifth button are connected to the first circuit board.

[0008] As a further technical solution of this utility model, the sixth, seventh, eighth, ninth, tenth and eleventh buttons are connected to the second circuit board.

[0009] As a further technical solution of this utility model, the first cover and the second cover are symmetrically distributed.

[0010] As a further technical solution of this utility model, a sealing strip is installed inside the groove at the bottom end of the bottom shell, and the sealing strip is made of silicone.

[0011] As a further technical solution of this utility model, the side of the bottom shell is provided with mounting screws, and the mounting screws are embedded in the mounting holes of the bottom shell.

[0012] As a further technical solution of this utility model, the surfaces of the first and second covers are coated with silver-gray paint.

[0013] As a further technical solution of this utility model, the surfaces of the front shell, the middle base and the bottom shell are coated with black paint.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the split-installed multi-function button switch for car steering wheels not only realizes the functions of easy positioning and installation, easy split operation, but also easy disassembly and maintenance.

[0015] (1) By setting a first cover, a shell, a middle seat, a limiting post, a bottom shell, a second cover, a first circuit board and a second circuit board, the first cover is installed on the left side of the steering wheel and the second cover is installed on the right side of the steering wheel. The shell and the limiting post at the bottom of the first cover and the second cover facilitate their stable positioning and installation on the steering wheel bracket. The first circuit board controls the buttons on the first cover and the second circuit board controls the buttons on the second cover. The separate installation and separate operation can improve the stability of the positioning installation.

[0016] (2) By setting a first button, a second button, a third button, a fourth button, a fifth button, a sixth button, a seventh button, a first circuit board, and a second circuit board, the multi-function buttons on the car steering wheel are installed separately by splitting them into a first cover on the left and a second cover on the right. The first circuit board controls the first button, the second button, the third button, the fourth button, and the fifth button, and the second circuit board controls the sixth button, the seventh button, the eighth button, the ninth button, the tenth button, and the eleventh button, so as to realize the function of separate control and installation.

[0017] (3) By setting a first cover, a second cover, a limiting post and mounting screws, the first cover and the second cover are installed separately. When disassembling and maintaining, only the first cover and the second cover need to be removed from the bottom shell. After disassembly, it is convenient to maintain the circuit board and buttons inside the first cover and the second cover. This structure realizes the function of easy disassembly and maintenance.
