Electrical initiator

An electrical initiator, comprising:

• a bridgewire capable of converting electrical energy to thermal energy;
• a primer covering the bridgewire;
• a flash charge covering the primer;
• and
• an output charge adjacent to the flash charge;
• wherein the primer includes
• about 30%-60% zirconium by weight;
• about 30%-60% KClO.sub.4 by weight;
• about 1%-10% flake aluminum by weight;
• about 2%-8% by weight of a compound selected from the group consisting of a styrene-ethylene-butylene-styrene copolymer, a styrene-ethylene-propylene copolymer, and a multi-arm ethylene-propylene copolymer;
• and
• about 0.1%-5% by weight of a styrene-ethylene-butylene-styrene copolymer functionalized with about 1% succinic anhydride.

An electrical initiator, comprising:

• a bridgewire capable of converting electrical energy to thermal energy;
• a primer covering the bridgewire;
• a flash charge covering the primer;
• an output charge adjacent to the flash charge;
• a non-conducting header with a first conducting means and a second conducting means passing through the header, first conducting means and the second conducting means connected to the bridgewire;
• an output cup including a dielectric material, the output cup coupled to the header and containing the primer, the flash charge, and the output charge;
• a conducting director can covering the output cup and connected to the non-conducting header;
• and
• a conducting stripe painted on an outside surface of the header touching the director can and ending closely adjacent to one of said first conducting means and said second conducting means.

An electrical initiator, comprising:

• a header;
• a first pin with a first inner end, the first inner end having a first head, the first pin passing through the header and the first head in close proximity to the header;
• a second pin with a second inner end, the second inner end having a second head, the second pin passing through the header and the second head in close proximity to the header;
• an electrically resistive device electrically coupled to and extending between the first head and the second head;
• a primer that includes a binder, wherein the primer is slurried in a solvent that is capable of dissolving the binder and wherein the slurried primer is applied to cover the electrically resistive device;
• and
• an inert material disposed on the header between the first head and the second head wherein the inert material adjoins the slurried primer to reduce the amount of slurried primer needed to cover the electrically resistive device and wherein the primer includes:
• about 1%-7% by weight of a compound selected from the group consisting of styrene-ethylene-butylene-styrene copolymer, a styrene-ethylene-propylene copolymer, and a multi-arm ethylene-propylene copolymer;
• and about 0.5%-4% by weight of a styrene-ethylene-butylene-styrene copolymer functionalized with about 1% succinic anhydride.
