Abstract

There is provided an electrical switch comprising a length of superconducting material. In some forms the electrical switch is configured to be controlled between a low-resistance state and a higher-resistance state by the selective application of one or more switching mechanisms. In the higher-resistance state, current flowing through the length of superconducting material may approach the critical current of the length of superconducting material, may be substantially equal to the critical current or may be greater than the critical current. In some forms, the length of superconducting material is a length of high temperature superconducting material. The switching mechanisms may comprise: heating the length of superconducting material; applying a magnetic field to the length of superconducting material; applying a time-varying magnetic field to create dynamic resistance and/or heat; and/or applying a time-varying magnetic field to a loop of superconducting material to create a screening current around the loop.
