摘要: The aim of the invention is to be able to reliably darken the EC mirror glass easily. To this end, a switching device (20) having at least one light guide (8, 8') is provided, with which at least the glare light (4) can be fed to the sensor (7). Said light guide can be placed at any suitable location in the rear-view mirror or inside the motor vehicle. The light is reliably fed to the sensor (7) by the light guide (8, 8'), and the sensor converts the light flux into an electrical signal for darkening the EC mirror glass.
