Abstract
This invention is a high voltage superconductor switch comprising: a length of superconductor having a switching portion located within an air gap; a magnetic circuit including at least one flux guide having ferrite pole pieces defining an air gap in which a switching portion of a superconductor can reside in use and at least one primary magnetic flux source located within the circuit so as to provide a quenching magnetic field across the air gap via the ferrite pole pieces.
