Abstract
Abstract A system for converting firearms to electrical ignition for firing of electrically primed ammunition. The system includes a drop in module to replace the conventional trigger, hammer pin, and other firing mechanism parts, and which has either included or separate structure to replace conventional firing pins. The module contains a safety interlock system, indicator lights, an on-off switch, an actuator switch, ammunition contacts and appropriate connecting circuitry to a power supply means.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
A system for converting firearms having a mechanical firing mechanism to electrical ignition for use with rounds of electrically primed ammunition which comprises a drop in module to replace said firing mechanism which includes an outer housing, a power source in said housing, circuitry means connected to said power source, said circuitry means being of all solid state construction, and said circuitry means is engaged with a round of ammunition to provide electrical power thereto to initiate combustion.
Claim 2
Independent Claim
78 words
A system for converting firearms having a mechanical firing mechanism to electrical ignition for use with rounds of electrically primed ammunition which comprises a drop in module to replace said firing mechanism which includes an outer housing, a power source in said housing, circuitry means connected to said power source, said circuitry means being of all solid state construction, and said circuitry means is engaged with a round of ammunition to provide electrical power thereto to initiate combustion.
Claim 3
Dependent Claim
22 words
A system for converting firearms as defined in claim 1 in which said power source is a battery carried within said housing.
Claim 4
Dependent Claim
21 words
A system for converting firearms as defined in claim 1 in which said circuitry means includes at least one safety switch.
Claim 5
Dependent Claim
25 words
