Automotive Limit Micro Switch for Sun Visor

This video by Unionwell takes you to understand the real application cases of automotive limit switches in automobiles. In addition, it is often used in automotive door lock switches.

The application of automotive limit switches in car sun visors, especially in sun visors with vanity mirrors, plays a key role. When the driver or passenger flips down the sun visor and opens the mirror cover, the micro switch is triggered to control the opening of the mirror headlight; when the sun visor is retracted or the mirror cover is closed, the light automatically turns off to ensure efficient energy use and improve user experience.
