[[Image:Pedersen Patent Toggle.GIF|thumb|right|Image from Pedersen patent describing toggle-delayed blowback mechanism as used in his rifle Toggle-delayed blowback is a firearm operating system whereby the rearward motion of the breechblock must overcome significant mechanical leverage. This mechanism was utilized on the Pedersen rifle and Schwarzlose MG M.07/12 machine gun.
A toggle lock pistol operates by utilizing blowback energy from a firearm cartridge to reload the weapon.[1] The breechbolt of the pistol is hinged in the middle and stationary at the rear end. The hinge is nearly straight. As the breech moves back under blowback power, the hinge joint moves upward. The leverage advantage keeps the breech from opening until the bullet has left the barrel and pressures have dropped to a safe level.[2]
