Definitions

  • the invention relates to a material for electrical contacts made of silver with 5 to 20% by weight of tin oxide and 0.05 to 5% of tungsten oxide.
  • the tungsten oxide also increased the security against the welding of switching contacts compared to pure silver-tin oxide. However, the forces required to separate the contacts were on average above the values of special silver-cadmium oxide materials.
  • this object was achieved in that the material additionally contains 0.1 to 5% by weight bismuth oxide.
  • the material made of silver with 5 to 20 wt.% Tin oxide, 0.05 to 5 wt.% Tungsten oxide and 0.1 to 5 wt.
