Disclosed, in a preferred embodiment, is a switching circuit incorporating a Field Effect Transistor (FET), two series dual-tap gas tube surge arrestors, and high-voltage resistors as part of a high voltage switch of a fireset for initiating an exploding foil initiator (EFI). Until energizing the FET via a firing command, an operating voltage of 1000 V is held off by a combination of the surge arrestors and high-voltage resistors. Upon receipt of a firing signal, a 28 V source is used to energize the FET that, in turn, decreases the voltage across the on...
