Abstract: Electrical contact device, in particular for low-voltage switches and contactors, comprising a contact element produced in one piece. Said contact element comprises in particular a first conducting area and a second contact area, said first area and said second area being produced with materials of different types. The device according to the invention is suitably produced through a sintering process of at least two powders of conductive material of different types, in order to define in said contact element a first conducting area produced with a first of said powders, and a second contact area produced with a second of said powders.
