damaged propeller from a Sopwith Baby aircraft 1916-1917 to demonstrate bulletholes with a machine gun fired behind the propeller without a synchronizer. The propeller needs to be replaced immediately after landing.
switch gear is a term that covers two related technologies.
The first is the timing gear, which is often mistakenly called interrupter gear "which is a triggering device attached to a machine gun armament of a fighter-type tractor so he would be the fire only at certain times. This allows the gun through the propeller arc without hitting the ball slides. Introduced during the First World War, the synchronizer weapon was an important development in history Air Combat and remained in operational service until the war in Korea, where the widespread adoption of jets made obsolete.
A real switch gear stopped firing the gun when a part of the aircraft was en route. For much of the early history of the fighter who was limited to the propeller. That would change with the introduction of the turret weapons first in bomber and briefly in the hunt.
Although their effects were the same, there is a subtle difference between the concept of the switch and the synchronizer. A machine gun fitted with a switch gear had the trigger normally activated and the mechanism of the switch that deactivates the trigger when a propeller blade was on the road. A machine gun fitted with timing devices had the trigger normally disabled and the synchronizer mechanism would allow the trigger when the propeller was clear. In reality, the technical difficulties related to the discontinuance of the reliability of a machine gun Maxim type means that there is no switch system of work has never been developed all implementations successfully used the concept of synchronization .

Origins
Testing the timing of firearms had been underway in France and Germany before the First World War, but the engineers involved received little support or encouragement of the army which ignored the need aircraft armed, believing only useful for recognition. The Swiss engineer Franz Schneider, working for Luftverkehrs Gesellschaft designed and patented a synchronizer 1913. French aircraft designer Raymond Saulnier built and patented a practical synchronizer weapon in April 1914, after having borrowed a gun from the Army for testing. No design has been developed to the point of being operational in the field, a major problem is the inconsistency of a propellant of ammunition to block shots.
Saulnier pursuing a simpler method using shielded propeller blades. In December 1914, French pilot Roland Garros Saulnier approach to organize the device must be installed on his plane, but it was not until March 1915 that took the air with a pre-fire Hotchkiss 8 mm (0,323 in) machine gun on his Morane-Saulnier Type L In addition to the CA.
