    Abstract: The present invention provides low-current carrying rem-reed switch contacts, preferably for operation under vacuum or under a protective gas. The contacts comprise a medium-hard magnetic material substrate which may contain anomalies on the surface. These are covered by an intermediate layer from 1 to 20 .mu.m of at least one metal selected from the group consisting of titanium, zirconium, hafnium, vanadium, niobium and tantalum. This intermediate layer is then covered with a noble metal layer, for example alloys of gold or silver, and preferably by ruthenium.

    Abstract: This invention relates to contacts which have about 0.001 to 96 percent by weight of ferromagnetic or ferrimagnetic permanent magnetic particles embedded in the contacts such that the magnetic particles are distinguishable from the basic contact material. The Curie temperature of the magnetic particles used in the contacts are greater than about 250* C. and the magnetic particles have an average spontaneous magnetic energy product greater than about 5,000 Gauss.Oersted. The magnetic particles having spontaneous magnetic energy can also be incorporated in certain contact configurations to also obtain excellent noise suppression characteristics.
