VanDevender, J P; Emin, D

A reusable fast opening switch is described for pulse power applications comprising: a pair of spaced, plate, conductors; a bulk magnetic semiconductor disposed between the conductors, the magnetic semiconductor being highly conductive below a critical temperature (T/sub C/) and rapidly transforming into an insulator above T/sub C/ by undergoing at least an order of magnitude change in resistivity for a temperature change 10/sup 0/C: and shock absorber means for protecting the semiconductor from shock waves generated during a resistivity transition.
