ABSTRACT:
An electrical trigger mechanism for a gun 1 has a relatively small and lightweight firing pin 5 which is held in its stationary position shown in outline 5.sup.1 by a permanent magnet 2 or the like and in which position the firing pin is spaced apart from a solenoid coil 4.
A capacitive discharge circuit discharges through the solenoid coil upon operation of the gun trigger, the movement of or pressure on the gun trigger being detected by any suitable triggering means such as an optical interrupter, a microswitch or a strain gauge. The energizing of the solenoid coil 4 is for a sufficiently short time that the magnetic field has decayed or substantially decayed by the time the firing pin reaches the coil 4. The firing pin is therefore not restrained as it passes through the coil 4 into an abuttment member 6 which has a substantially central aperture through which the firing pin 4 can project in impacting against the bullet or cartridge 9 in position within the barrel 8. After firing, the permanent magnet 2 or the like will attract the firing pin 5 back into the stationary position ready for the next firing.
