The article considers a mathematical model for determination of transition resistance in electrical contacts. The suggested model considers elastic, elastoplastic and plastic deformations of micro-protrusions on rough contact surfaces, the presence of surface films and dust particles on them. A theoretical dependence of possible contact failure on dust content has been obtained.
