Abstract
A crowbar switch having a start and a crowbar gap each having a trigger electrode therein. The two gaps are disposed close to each other so that the photons and thermoelectrons emitted from the arc produced by a discharge in the start gap ionize the ambient gas about the crowbar gap for easier occurrence of a discharge in the crowbar gap.
