A method is described for maintaining silver cadmium oxide alloy tips of an electrical contactor clean and substantially free of contamination involving operating the electrical contactor normally, under its regular working operation, in a cold switching mode, and at intervals of time, separating the tips under a load condition. A procedure is described also for determining at what interval the tips should be separated under the load condition. Apparatus is described that will operate to perform this method automatically.
