Pyrotechnic Switch

Abstract

A pyrotechnic switch which is non-conducting before actuation and fully conducting after actuation has been developed. The switch utilizes the principle that a pyrotechnic composition containing oxides and a fuel has a very high electrical resistance prior to ignition. However, after ignition the oxide is converted to a low resistance metal slag which makes contact between two points in a switch. (Author)
