Beschreibung
Zusammenfassung:	An electric contact device for conveying electric current to an article such as a moving billet or wire comprising a current feeder member in a bed of electrically conductive de-oxidized metal particles and the article being placed in contact with the bed. The particles may be copper particles and the bed may be fluidized with a non-oxidizing gas and be maintained in a non-oxidizing atmosphere. Two contact devices may be provided at spaced positions to cause a current flow along the article. The contact device may operate as a switch by providing means to move the article into and out of the bed.
