[origin: US5429656A] PCT No. PCT/DE92/00388 Sec. 371 Date Nov. 24, 1993 Sec. 102(e) Date Nov. 24, 1993 PCT Filed May 14, 1992 PCT Pub. No. WO92/22080 PCT Pub. Date Dec. 10, 1992.In particular for contacts in low-voltage switches, the contact material consists of silver and further active components. In accordance with the invention, there are present as active components, in combination, iron oxide (Fe2O3/Fe3O4) in a proportion of between 1 and 50% by weight and at least one oxide of a further chemical element in a proportion of between 0.01 and 5% by weight. In particular, contact materials of the constitution AgFe2O3ReO2 and AgFe2O3ZrO2 have proven suitable in practice. The manufacture of the material and fabricating of the contacts can be effected by methods of powder metallurgy with the inclusion of molding or extrusion technique.
