ABSTRACT:
An igniter assembly with a housing, an initiator, an input charge, a first barrier, a second barrier, and an output charge. The input charge is formed of a secondary explosive and disposed adjacent the initiator. The first barrier cooperates with the housing to form a chamber into which the input charge is received. The second barrier is disposed on a side of the first barrier opposite the input charge and combusts in response to energy released during detonation of the input charge. The output charge is formed of a pyrotechnic material and disposed on a side of the second barrier opposite the first barrier. The output charge can combust in response to energy released during combustion of the second barrier. The housing and the first barrier cooperate to isolate the output charge from heat and pressure generated by the input charge if the input charge is cooked-off.
