Abstract
A switch for use in an inductive energy store transfer circuit utilizes a quantity of electrically conductive liquid bidirectionally flowable between a position that establishes electrical connection between electrodes and a position that opens electrical connection between the electrodes. High pressure gas biases the liquid to a position that establishes electrical connection between the electrodes, and yieldably resists movement of the liquid toward the position that opens electrical connection between the electrodes. Current through the switch electrodes produces a magnetic force that acts on the liquid and urges it toward the position that opens electrical connection between the electrodes. Switching action occurs upon a predetermined magnitude of current being attained.
