1. A piezoelectrically controlled superconducting switch comprising:

  • a substrate;

    a superconductor which is bonded to the substrate; and

    a piezoelectric subassembly for straining a portion of the superconductor between a normal unstrained condition and an induced strained condition;

    said piezoelectric subassembly having a load-applying means for causing strain in the superconductor portion, wherein the load applying means includes a piezoelectric transducer for applying a bending moment to the superconductor and the substrate, and including a first support arm and a second support arm spaced apart and extending from a base plate for holding the substrate at opposite edges thereof and for positioning the piezoelectric transducer.
