Реферат: Devices for the management of contact spots, partly consisting of surface plating, partly of surface polishing and partly of substrate surface profiling in the form of parallel grooves stretched out in the direction of sliding and/or of isolated asperities. The management of the contact spots is designated to generate, at electrical brush interfaces, a large number of contact spots of pre-determined shapes and distribution that promote low electrical contact resistance and long wear life. Preferably, the substrate is coated with a hard, highly conductive coating that is resistant to wear and chemical attack. The invention is similarly applicable also to electrical switches wherein it will assure reduction of interfacial resistance as well as of sticking forces. Finally, it may also be used for the efficient transfer of heat across interfaces.
