　　Features of automotive electrical switches
　　1. Under the premise of good performance, not only the appearance should be beautiful, but also the color of the surface must be coordinated with the tone of the whole car interior decoration, so as to improve the appearance of the whole car.
　　2. Safety factors shall be considered in the design. In case of an accident, the vehicle shall not cause injury to the occupant or reduce the injury degree to the minimum. For example, the button is designed to be rounded, the length of the handle is shortened as far as possible, and the switch is fixed and embedded in the panel. Also must consider the fire safety of the vehicle, for the switch to use materials to use flame retardant materials.
　　3. The external shape design of automobile switch must take into account the installation location, operation mode, operation feeling and other factors, and it is necessary to design and arrange according to the man-machine theory.
　　4. The voltage levels are 6v(motorcycle), 12v(car) and 24v(diesel car). In the 21st century, there may be 42v voltage levels in cars.
　　5. According to different control objects, its working mode includes instantaneous, short-term and continuous operation. Its load current can be from lma-1000a depending on the purpose.
　　6. Considering the reliability, the switch, like other auto parts, will always be subjected to the impact and vibration of forces in all directions in the process of driving, resulting in early damage and rivet looseness of switch parts. In addition, the car will also be affected by the temperature, relative humidity and other harsh environment, causing the switch contact oxidation intensified, resulting in shortened switch life.
