Isolated paths connector

An electrical one piece connector in the form of a sheet having a thickness between 1 to 100 mils and having top and bottom surfaces and which comprises a homogeneous mixture of a flexible insulator material binder, which is a thermosetting plastic, thermoplastic or an elastomer, and electrically conductive particles, said connector having means for providing at least when uncompressed a low through resistance of less than 1,000 ohms between opposite aligned points on said top and bottom surfaces as well as a high isolation resistance, which is greater than 100,000 ohms, along the top and bottom surfaces between points at a distance apart equal to five times the thickness of the connector between said top and bottom surfaces further characterized in that the connector exhibits said low through resistance through the volume between aligned opposed electrical contacts placed on opposite top and bottom surfaces thereof merely in surface contact therewith and said high isolation resistance between diagonal electrical contacts placed on opposite top and bottom surfaces thereof as well as between adjacent electrical contacts placed on the same surface thereof all merely in surface contact therewith at a distance apart equal to five times the thickness of the connector between said top and bottom surfaces, and in which the connector contains less than 20 volume percent of electrically conductive particles.
