Abstract:

The electrically initiated squib of this invention is comprised of a plug member with a pair of spaced apart electrical leads extending through the plug member into a holder member for containing a predetermined quantity of an easily-ignitable composition. A bridgewire that is constructed of a bimetallic composite Pyrofuze selected from palladium and aluminum, platinum and aluminum, and ruthenium-palladium alloy and aluminum is secured between the electrical lead ends that terminate in the holder member of the squib. The holder member is loaded with a loose, easily-ignitable composition which is a finely-ground and intimate mixture of a pyrotechnic which is a composition selected from the group consisting of 45 by weight zirconium and 55 by weight potassium perchlorate, 20 by weight boron and 80 by weight potassium nitrate, 45 by weight aluminum flake 17 to 44 microns and 55 by weight potassium perchlorate 6 to 17 microns, and lead azide or lead styphnate, or a single-base, a double-base, or composite propellant composition in a powder or pellet form.
