    摘要: A needle 2 includes a plunger member 21 and a collar member 22, and is provided to be reciprocable from a latch position to a latch release position inside a stator 1. A first magnet coil 31 has sufficient electromagnetic power to put in a latch state the needle 2 which is in a latch release state on energization. A permanent magnet 4 has sufficient absorption power for absorbing a collar member 22 of the needle 2 put in the latch state by the electromagnetic power of the first magnet coil 31 and maintaining the latch state even when the first magnet coil 31 is in a non-energized state. A second magnet coil 32 can diminish magnetic fluxes of the permanent magnet 4 and change the needle 2 from the latch state to the latch release state on energization. Thus, energy efficiency is improved by varying how to energize the magnet coils according to the state of a load side.

    摘要: In a closing magnetic circuit, when a movable contact is in contact with a fixed contact and a switching device is closed, N and S poles of a permanent magnet attract the fixed member in a direction in which the movable contact is pressed against the fixed contact. In an opening magnetic circuit, when the movable contact is separated from the fixed contact and the switching device is open, one of the N and S poles of the permanent magnet attracts the fixed member in a direction in which the movable contact is separated from the fixed contact. An operating electromagnet winding increases and decreases the magnetism in the closing magnetic circuit and opening magnetic circuit. With this configuration, it is possible to realize an operating apparatus for a switching device using a simple mechanism and assure a stable operation by producing a great contact load.

    摘要: {W—CuxSb-balance Cu} alloy is employed for contacts. As the anti-arcing constituent in the alloy W or WMo in a content of 65 to 85%, of grain diameter 0.4 to 9 &mgr;m is employed. As auxiliary constituent, CuxSb is employed, the content of the CuxSb being 0.09 to 1.4 weight %, the x being x=1.9 to 5.5, the grain diameter being 0.02 to 20 &mgr;m, and the mean distance between grains being 0.2 to 300 &mgr;m. As conductive constituent, Cu or CuSb solid solution is employed, the Sb content present in solid solution form in the CuSb solid solution being less than 0.5%. As a result, not only is dispersion of CuxSb, which is evaporated on subjection to arcing, reduced, but also generation of severe cracks, which have an adverse effect in terms of occurrence of restriking. Arcing at the contacts surfaces is prevented, suppressing dispersion and exfoliation of W grains. In this way, damage due to melting and dispersion at the contacts surfaces is reduced, enabling both restriking to be prevented and the contact resistance characteristic to be improved.
