Reed sensors in Automobile Sun Visors

Automobile Sun Visor
Automobile Sun Visor

Automobiles are fitted with visors that can be swiveled downwards and outwards to block the sun from the driver or passenger’s eyes. These visors also come with a vanity mirror under it that may have a slide that turns on a tiny lamp for use of the mirror at nights. Closing the slide over the mirror turns the lamp off and also protects the mirror. If by chance the light is turned on and the sun visor is closed without closing the sliding door, the lamp should switch off. This is achieved by wiring a reed sensor inside the shaft with a magnet on the swiveling visor which shuts off the lamp when the visor is closed. A reed sensor and a magnet is also used in the sliding mirror assembly to turn off the lamp when the slide is closed.
