摘要： An electric switch having a dry electrically insulating film bonded permanently to one of two proximate facing surfaces of a pair of relatively movable ceramic members, such as facing generally cylindrical surfaces of rotor and stator members. The film reduces friction while acting as an electrical insulator and serves a very important function in preventing interengagement of the surfaces to thereby prevent the formation of ceramic dust particles which might otherwise engage between electrical contacts carried by the ceramic members. The film preferably is heat bonded to the surface and may comprise a tetrafluoroethylene (teflon) combined with either a bonding resin material or a water base with modifiers, or a molybdenum, tungsten or other metal sulfide combined with a sodium silicate or with isopropanol. Further important features relate to methods by which dry film lubricants of superior qualities are obtained, firmly bonded to the surface.
