Figure 1-3As shown, a modular customizable steering wheel switch assembly of the present invention comprises a base plate 1, a plug-in ring 3 is provided on one side of the base plate 1, a circuit board 4 is fixed inside the plug-in ring 3 by bolts, a button switch 5 is equidistantly embedded on one side of the circuit board 4, and a housing 2 is sleeved on one side of the base plate 1 located outside the plug-in ring 3;

[0022] A structural frame 6 is provided inside the shell 2, and a rod sleeve 7 is equidistantly inserted into the structural frame 6. A push rod 8 is inserted into the rod sleeve 7. A spherical block 11 is provided at one end of the push rod 8. A compression spring 10 is sleeved on the outer side of one end of the push rod 8. A pressing button 9 is embedded on one side of the shell 2.

[0023] When in use, the shell 2 is sleeved on one side of the base plate 1, which is convenient for installation and disassembly. Pressing the push button 9 pushes the push button switch 5 through the push rod 8. The push button switch 5 turns on or off to give an electrical signal to the circuit board 4. The push button switch 5, the push rod 8 and the push button 9 are all designed in a socket style, which is convenient for replacement and customization.

[0024] For example, Figure 1 As shown, the present invention further includes that a connection harness 15 is welded on one side of the circuit board 4 away from the button switch 5 , and a connector 16 is provided on the end of the connection harness 15 on the other side of the base plate 1 .
