ABSTRACT:
A superconductive switch has a first layer of a superconductive coil wire wound around a shaft clockwise from the first end to the middle and counterclockwise from the middle to the second end. A second layer of the wire is wound around the first layer in identical fashion. A third layer of the wire is wound around the second layer counterclockwise from the first end to the middle and clockwise from the middle to the second end. An electrical heater is located between the first and second layers, and a stratum of electrical insulation, discrete from that of the coil wire, is located between the second and third layers.
