Abstract: The flow characteristics of electrical signal current between co-operating electrical contact surfaces may be enhanced, such as by reducing or eliminating contact-to-contact surface resistance, zero-crossing distortion, harmonic distortion, etc. By coating at least one of a pair of co-operating electrical contact surfaces, usually before they are plugged together, both of the co-operating contact surfaces will have at least a substantial portion of each surface coated by at least a very thin film of contact stabilization material, and thereby achieve enhanced signal current flow characteristics. The contact stabilization material comprises at least one block polymer or co-polymer of polyoxypropylene together with polyoxyethylene.
