[0007] A car steering wheel key switch structure comprises: a base body, on which a first tact switch, a second tact switch, a third tact switch, a fourth tact switch and a fifth tact switch are respectively arranged, a first pressing block is arranged on the top of the first tact switch, a second pressing block is arranged on the top of the second tact switch, the third tact switch, the fourth tact switch and the fifth tact switch, a lever is connected to the top of the first pressing block, a guide rib groove is arranged on the top of the second pressing block, a rotating disk is provided on the lever sleeve, first pressing plates are respectively arranged on both sides of the rotating disk, the first pressing plates are respectively clamped in the guide rib grooves of the second tact switch and the fourth tact switch, a rotating shaft is respectively arranged on the other two sides of the rotating disk, a second pressing plate is respectively sleeved on the rotating shaft, and the second pressing plate is respectively clamped in the guide rib grooves of the first tact switch and the fifth tact switch.

[0008] Furthermore, a matching shell is provided at the top of the base, and the lever penetrates through the shell and extends to the top of the shell.

[0009] Furthermore, the top end of the lever is connected to a dial.

[0010] Furthermore, the lever is a hollow structure, and guide members are respectively provided inside the lever.

[0011] Furthermore, a locking pin is provided at the bottom end of the base.

[0012] Beneficial effects of the utility model:

[0013] The utility model realizes the switching of the first light touch switch by pressing the lever downward in linkage with the first pressure block to touch the first light touch switch. At the same time, by toggling the lever to apply force to either side, the lever cooperates with the first pressure plate or the second pressure plate and the guide rib groove and the second pressure block to touch the second light touch switch, the third light touch switch, the fourth light touch switch and the fifth light touch switch, thereby realizing the switching of multiple functions by a single lever, making the function-intensive operation more convenient.
