A testing bed for use in testing printed circuit boards and the like includes a light-transmissive supporting member, a plurality of spaced strips of light-transmissive, electrically-conductive material on one face of the supporting member, and a plurality of probe elements overlying and in contact with the strips. Each of the probe elements includes an outer electrically-conductive contact point for contact with a pad of the article to be tested. A photoconductive material between the probe elements and the strip forms a photoconductive gate.
