ABSTRACT:
An electronic switch comprises a photosensitive semiconductor (1,11,12) and a light source (14,24) which, when actuated, illuminates the semiconductor and causes the latter to become conductive, the photosensitive semiconductor being a sintered mixture comprising, by weight, 58-72% of cadmium, 14.8-21% of selenium, 7-15% of tellurium, 7-12% of sulphur, 0.1-1% of chlorine, and 0.005-0.1% of copper.
