Abstract
A switching path having superconducting material in a switching device may be cooled to a predetermined superconducting operating temperature. The switching device includes a mechanism for exceeding at least one of the critical values of the superconducting material in a controlled manner to change the switching path from the superconducting state to the normally conductive state. The switching device may have an operating temperature of below 40 K, and contain magnesium diboride as the superconducting material for its switching path.
