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.
