A Glock switch functions by applying force to a semi-automatic pistol's trigger bar to prevent it from limiting fire to one round of ammunition per trigger pull. [5] [6] Normally, in a semiautomatic pistol, after firing, the trigger bar catches the firing pin until the trigger is released, but when depressed by the switch it does not catch.
A forced reset trigger (or "hard reset" trigger) is a device that allows a person to fire a semi-automatic firearm at an increased rate. The forced reset trigger works by mechanically resetting the trigger's position after a shot is fired. This allows for an increased rate of fire.
Examples of the variety of typical semi-auto mechanisms are a stiff double-action trigger pull with the safety off (Beretta 92F/FS), a double-action with no external safety (SIG Sauer P-series, or Kel-Tec P-32), or a crisp single-action trigger pull with a manual safety engaged (M1911, FN Five-seven and certain configurations of the HK USP).

When an automatic sear is in place, the weapon’s trigger bar is prevented from catching its firing pin, allowing multiple rounds to be fired without additional pulls of the trigger.
Handguns and rifles illegally modified with devices called “Glock switches” to become machine guns have proliferated, officials say. The devices are tiny, cheap and easy to install.
Firearms use triggers to initiate the firing of a cartridge seated within the gun barrel chamber.This is accomplished by actuating a striking device through a combination of mainspring (which stores elastic energy), a trap mechanism that can hold the spring under tension, an intermediate mechanism to transmit the kinetic energy from the spring releasing, and a firing pin to eventually strike ...
However, because of the spring tension placed on the disconnector by the firing pin block, the weight of the trigger pull is significantly increased. Trigger pull is related to the interaction of the sear with the trigger and the spring. It can be measured, regulated and adjusted, but it is a complicated mechanical problem. [2]
