The ignition source was an igniter made from platinum wire. A platinum igniter provided the source of ignition. The Space Shuttle Main Engine hydrogen oxygen propellant mixture was ignited with a spark igniter. Consists of a projectile, a propellant cartridge and primer or igniter tube. A simple solid rocket motor consists of a casing, nozzle, grain (propellant charge), and igniter. Each "can" has its own fuel injector, igniter, liner, and casing. Electronic ballasts include the igniter circuit in one package. A detonation is initiated in the fuel/oxidizer mixture by some form of igniter. The M116 series is usually fitted with a pull string igniter and fuze assembly. The YF-94A's afterburner had many teething problems with its igniter and the flame stabilization system. The term "solid rocket motor" applied to the propellant, case, igniter and nozzle. Pellet stoves can either be lit manually or through an automatic igniter. The Ignatron had a cathode, anode and an igniter. The "strike" requires an electrical circuit with an "igniter" and a ballast. It was usually detonated with a pull igniter.
