[0002] With the development of automobiles, people are pursuing higher and higher quality in automobiles, and the requirements for the operating comfort of combination switches (control switches) are also increasing, especially in the feel and sound of handle operation. In the past, combination switches were only limited to meeting functional requirements.

[0003] The existing control switch includes a shell, a steering bracket arranged in the shell, and a handle rotatably arranged on the shell. The handle is connected to the steering bracket and rotates synchronously. The steering bracket is connected to the shell and rotates relative to the shell under the drive of the handle. However, the connection between the shell and the steering bracket adopts the matching of plastic parts and metal parts. However, under the influence of the environment, the plastic parts fluctuate, and the metal parts remain unchanged. Therefore, the handle is prone to jamming during operation, the operating feel is poor, and the recognition signal is affected, and the corresponding indication action cannot be accurately made.
