A pyrotechnic initiator having a bridgewire configured in an enhanced heat-sinking relationship with the adjacent ignition charge and/or header glass surface without the necessity of a consolidation force.


1. An initiator comprising:a) a header assembly including an eyelet, a glass insulator and a first pin defining a top surface, and an exposed electrical initiating element in intimate contact with said glass insulator; and,b) an ignition charge adjacent to said top surface of said header assembly, said ignition charge being monolithic and adjacent to and in heat-transferring relationship with said electrical initiating element, said ignition charge not being pressed against said top surface of said header assembly by a pressure of more than 50 psi. 2. Th...
