Out-of-line interrupter ignition system for flares and markers

摘要

A hollow pivot pin, with an exposed primer at its side, holds boron potassium nitrate pellets 78 for igniting a flare. A spring-loaded firing pin mechanism is attached radially to the pivot pin and is swung about it by a parachute lanyard. When the firing pin becomes aligned with the primer charge, the firing pin is released and fires the charge.
