    摘要: There are provided a contact construction for DC loads which, even in the case of a high-capacitance load, can be repeatedly cut off for a long term without causing any problems such as cut-off failure, locking and deposition due to an abnormal continuation of an arc between the contacts, burning and destruction of the contacts, and an increase in contact resistance, and whose reductions in size and cost can be achieved, as well as a switching device having the contact construction. The contact construction includes a stationary contact and a movable contact that are opposite to each other, and a magnetic unit which applies a magnetic field acting in a direction orthogonal to a moving direction of the movable contact, to a space in which both contacts exist, and one of the stationary contact and the movable contact is used as an anode-side contact, and the other is used as a cathode-side contact. In the contact construction, the anode-side contact is made of an AgSnO2-based alloy which contains at least Ag and SnO2, and the cathode-side contact is made of one of an AgNi-based alloy which contains at least Ag and Ni and an AgCuO-based alloy which contains Ag and CuO. The switching device has the above-mentioned contact construction.

    摘要: A powder metallurgy material for use in the manufacture of electrical contacts and having enhanced cold workability consists essentially, by weight percent, of 5 to 20% tin oxide, 2000 to 5000 ppm, preferably 2000 to less than 4000 ppm copper, 20 to 200 ppm, preferably 20 to 100 ppm, lithium, balance silver. Such materials are produced by compacting the powdered components and heating to sinter the material to at least 93% of theoretical density. Such materials subsequently can be hot or cold worked to a form useful for the manufacture of electrical contacts.

    摘要: Electrical contact materials made from an internally oxidized Ag alloy containing 0.5 to 12 weight % of Sn. Internal oxidized structures which have been produced in the alloy at the forwardmost area along a progressive direction of internal oxidation and which are fine and free from the segregation of tin oxides, are employed as contact surfaces. Another surface opposite to said contact surfaces may be brazeable by having it subjected to a reduction or decomposition treatment of metal oxides about said another surface.

    摘要: Rather high temperature raise of internally oxidized Ag-Sn alloy contact materials due to a high contact resistance inherent to such materials, is eliminated. The high contact resistance which is caused by high concentration or supersaturation of metal oxides including tin oxides about contact surfaces, is avoided by having solute metals sublimated, reduced or extracted about the contact surface before the internal oxidation thereof. Sublimation and other treatments may be made after having the materials subjected to internal oxidation.

C. into a mass in which said pieces coalesce to each other without any distinctive silver interface thereamong, and through which tin oxides are uniformly dispersed substantially without any grain boundaries.
