Abstract

An enhanced ignitor for initiating a quantity of pyrotechnic, explosive or energetic material including a multistage device in which the semiconductor bridge ignitor (10) is activated by an energy-generating component (15) which upon activation alloys, crystallizes or otherwise reacts to create sufficient ignition energy to cause the pyrotechnic explosive or energetic material to ignite.
