Abstract(in English) In this paper, experimental data of non-arcing circuit breaking phenomena in electrical contacts are presented. A dark bridge that is a non-luminous bridge between electrical contacts is an effective factor for the non-arcing circuit break. A facility of a cantilever system was established to precisely control a position of an electrode. By using this facility, dark bridges between contacts were made and the dark bridges were observed by a microscopic camera system
