Abstract: A female contact of an interrupter includes a number of flexible fingers in a cylindrical array defining a cavity toward the axis of which the fingers are biased. A pair of semi-annular refractory members are located at the free ends of the fingers and define a passageway which is continuous with the cavity. The members are not welded or brazed to the fingers and are, accordingly, transversely free-floating relative to the fingers; they can move laterally of the axis independently of the fingers, but are prevented from movement along the axis. When a male contact is out of the cavity and the passageway, the fingers act against the exterior of the members until facing stop surfaces on the members abut, setting the minimum size of the passageway, which is smaller than the diametric size of the male contact but larger than the diametric size of the cavity between contact buttons on the fingers.

Abstract: A coaxial, polarity-reversing switch for insertion and electrical connect into a coaxial power transmission line with both switch and line designed for carrying high direct current, but useable with alternating current systems. Since stray or external magnetic fields are best contained in coaxial transmission lines, this coaxial switch best maintains this desired relationship. A reciprocatable shuttle, movable axially within the body of the switch, has multi-louvered contact material containing many areas of contact to conduct the high current. In one shuttle position the switch maintains forward polarity; in the central position, the switch is off; in a third position, the polarity of the conductors in the coaxial line is reversed. Thus the switch is a DPDT center-off type, non-conductive coolant may be circulated through passages in the switch and when used may be sealed in the switch with suitable seals.

The frictional connection between the conductors and the slip ring holds the slip ring from being fully drawn out of contact with both conductors when the locking cyclinder is turned from closed to neutral position and holds the slip ring from being drawn into contact with both conductors when the locking cylinder is turned from open to neutral position.
