Optoelectronic touch or proximity switch

摘要

The arrangement has a light beam radiator in a transparent housing, a photosensitive element receiver outside the light path from the radiator and a transparent surface in the light path that reflects light to the receiver if touched or approached. The transparent surface is formed by the housing, which acts as a light conductor and the photosensitive element is arranged immediately close to and outside the housing in the radiation direction. The arrangement has a light beam radiator (1) in a transparent housing (2), a photosensitive element (4) as a receiver arranged outside the light path (3) from the radiator and a transparent surface in the light path that reflects the light to the receiver if touched or approached. The transparent surface is formed by the transparent housing, which acts as a light conductor and the photosensitive element is arranged immediately close to and outside the housing in the radiation direction. AN Independent claim is also included for the following: an illuminated light sensitive switch.
