A plane-board explosive opening switch and its preliminary reasearch results are presented in this<br />

paper. The opening switch consists of an explosive network board,a folded metal foil and<br />

insulating slots. When used as opening switch in inductive energy storage system, it can transfer<br />

pulse current with tens of kilo-ampere and more than 20μs rise time from primary energy source<br />

to a 50nH load in less than 2μs.The conversion efficiency is more than 90%.
