A switch attached to a Glock pistol. A Glock switch (sometimes called a button or a giggle switch) [1] [2] [3] is a small device that can be attached to the rear of the slide of a Glock handgun, changing the semi-automatic pistol into a selective fire machine pistol capable of fully automatic fire.
An auto sear ("automatic sear") is a part of an automatic firearm that holds the hammer in the cocked position while the bolt of the weapon is cycling and releases the hammer/striker. It is basically an internal trigger actuated by the bolt/bolt carrier when placed in-battery. An auto sear is required in nearly every automatic rifle.
In a firearm, the sear is the part of the trigger mechanism that holds the hammer, striker, or bolt back until the correct amount of pressure has been applied to the trigger, at which point the hammer, striker, or bolt is released to discharge the weapon. The sear may be a separate part or can be a surface incorporated into the trigger.

In an open-bolt gun firing semi-automatically, the bolt is caught and held at this point by the sear after each shot; and in automatic open-bolt fire, it's caught and held in this manner whenever the trigger is released. In contrast to this, in closed-bolt guns, the trigger and sear do not affect the movement of the bolt directly.
The sear bar on the Type 94 Nambu converts the forward pull of the trigger into a lateral movement that frees the hammer. [19] Because the sear bar is on the outside of the pistol, [ 19 ] it can be accidentally discharged if the pistol is cocked and handled carelessly. [ 6 ]
