    Abstract: A magnetically actuated switching device using reversibly magnetizable armatures treated by a selective annealing process. The annealing process changes the homogeneous coercive magnetic properties of the armatures so that the highest coercive force is caused to occur in the region of the armature which is subjected to magnetizing forces from an energizing coil, and the region of the armature existing outside the magnetizing field is annealed in a manner to lower the coercive force of the armature. Selectively annealing the armature to provide high coercive force in the vicinity of the magnetizing coil reduces the amount of magnetizing force necessary to be supplied by the coil for switching the armature from a closed to an open contact position.

    Abstract: The cooperating contacts of a reed switch are made of rhodium oxide. Such contacts are prepared by plating rhodium on the reeds of reed switches and then oxidizing the surface layers of the plated rhodium contacts by heating them in an oxygen containing atmosphere at a temperature of from 380* to 580* C for 3 to 15 minutes.

    Abstract: A METHOD OF PRODUCING THE CONTACT POINT COATING FOR A RELAY CONTACT OF ONE TYPE WHEREIN THE CONTACT IS MADE OF AN IRON-NICKEL ALLOY, E.G. AS USED IN REED AND SIMILAR TYPE RELAYS. A LAYER OF GOLD IS INITIALLY APPLIED TO THE CONTACT POINT OF THE CONTACT AND THE CONTACT IS THEN TEMPERED AT A TEMPERATURE BETWEEN 700 AND 1000*C. THEREAFTER, A LAYER OF A TWO-COMPONENT ALLOY CONSISTING ESSENTIALLY OF GOLD

    AND EITHER COBALT, NICKEL OR CHROMIUM IS DEPOSITED ON THE GOLD LAYER EITHER GALVANICALLY OR BY CATHODE SPUTTERING. FINALLY THE COATING MAY BE THERMALLY HARDENED BY A SHORT TIME FURTHER TEMPERING AT APPROXIMATELY 800*C. PREFERABLY IN A REDUCING ATMOSPHERE.
