With the development of society, the comfort and maneuverability of automobiles are more and more concerned by people. In order to meet people's needs, multifunctional steering wheel switch as an important operating part of the car, integrated with a number of functional buttons, the advantage is that the driver does not need to have too much action can be convenient to control the more functional functions in the car. At the same time, it is required to be beautiful in appearance, comprehensive in function, quick in response, good in feel and durable.

Due to the limited space of the steering wheel switch, the function buttons with higher frequency of use are generally arranged on the steering wheel switch. General steering wheel switch functions mainly include: cruise on/off, instrument information display control, audio control buttons, Bluetooth control buttons and voice control buttons, etc., in addition to the realization of the horn function. At the same time, night lighting requires the switch buttons to be backlit.

An automotive multifunction steering wheel switch is a control device integrated into the steering wheel to facilitate the driver's control of the vehicle's various functions and systems. It usually contains multiple buttons, switches, and wheels that control the audio system, phone calls, cruise control, vehicle information display, and other functions. The following is a brief discussion on the design of automotive multifunction steering wheel switch functions:

When designing a multifunction steering wheel switch, you need to consider the layout and grouping of buttons and control elements. A common design is to group functions according to categories, for example, audio control buttons are placed in one group, telephone control buttons in another group, and cruise control buttons in another group. Such a layout helps the driver to quickly find the function they need and reduces the fragmentation of operations. The priority and importance of frequently used functions also need to be considered. For example, buttons for volume control and switching songs are usually placed in easier-to-operate locations because drivers are likely to use these functions frequently. The distribution of functions should be adapted to user habits and the needs of specific markets to provide the best user experience.

For safety reasons, buttons and control elements should be laid out in such a way as to avoid interfering with the driver's normal driving operations to prevent inadvertent touches and distractions. In addition, some critical functions (e.g. emergency braking, airbags, etc.) may require additional protection, such as double confirmation or anti-touch design.

Multi-function steering wheel switch is one of the most frequently operated and used parts in automobiles, which is an important manifestation of automobile digitalization and intelligence. The automobile market is highly competitive, and it is necessary to keep up with the market demand and accelerate the renewal of products. Consider the frequency of use of the function first to determine the layout of each key, select the appropriate type and size of the key from the function of the key, control the quality and cost of the product from the structure and circuit design, and constantly study the characteristics and technical advantages of the switch of each car model to continuously improve the quality of the steering wheel switch and the user's perception.
