Abstract:
A firing probe assembly for use in a firearm having a firing apparatus adapted to fire a non-impact fired cartridge, said firing probe assembly comprising:a conductive probe shaft immovably mounted on a frame of said firearm and in electrical communication with said firing apparatus; a probe tip reciprocally slidable relative to said probe shaft for movement into and out of contact with said cartridge; a probe spring engaged between said probe tip and said probe shaft for electrically engaging said probe shaft with said probe tip and urging said probe tip toward contact with said cartridge; and a dielectric annular actuator bushing slidably disposed within a countersunk bore of said frame and having an exterior shoulder bearing against a bushing spring seated within said frame bore, said actuator bushing defining an inner bore having an annular bearing surface engageable with said probe tip, said bushing spring positioned within said frame to resist forward movement of said actuator bushing and having an annular bearing surface facing rearwardly and positioned to be engaged and moved axially by a firing mechanism of the firearm, said actuator bushing being slidable fore and aft within said frame to govern fore and aft movement of said probe tip in response to actuation of said firing mechanism.
