ABSTRACT:
An opening switch device for interrupting the flow of high amperage currents such as those which occur in inductive energy storage systems is disclosed. The opening switch includes a plasma focus device incorporating an auxiliary electrode through which the current to be interrupted flows. This current is interrupted due to the enhanced resistance which occurs in the plasma focus device. A second embodiment of the plasma focus switch includes the application of an external magnetic field which is compressed by the plasma focus effect along with the current flowing through the auxiliary electrode.
