Abstract
According to one embodiment, a proximity switch comprises a radiation emitter for emitting radiation, at least one photosensor for detecting light levels near the radiation emitter, and an electronic circuit for energizing the radiation emitter and for receiving and processing signals from the photosensor so as to perform a specified function upon detecting an object that causes the radiation emitted from the radiation emitter to be reflected back to the photosensor. According to another embodiment, a rearview assembly for a vehicle comprises a transparent housing.
