Abstract
1369382 Semi-conductor switching circuits ITT INDUSTRIES Inc 20 July 1972 [27 July 1971] 34013/72 Heading H3T [Also in Divisions G1 and H1] In an electrical relay arrangement, an input signal is rectified by a bridge rectifier and applied to a constant current circuit which supplies current to an oscillator feeding the primary winding 2 of a transformer 1. The secondary winding 3 of the transformer is connected to a trigger circuit feeding the output terminals of the relay. The input and output circuits of the relay arrangement to the left and right respectively of the line 4 are housed in separate insulating parallelepipedal boxes with the transformer windings adjacent juxtaposable faces.
