Airsoft AUG two-stage micro switch

thingiverse

This custom trigger system is designed specifically for HPA or micro controller based AEG systems that utilize mechanical switches to control trigger pulls. The print provides mounting points for two micro switches and does nothing else. The first version of this two-stage trigger replaces the original AUG AEG trigger board, serving as an experimental solution that works in practice despite being somewhat janky. Feel free to modify it as needed. For installation, you will need two M2 screws, a 3mm steel rod for the trigger axle, and 2x 3x6x2.5 ball bearings for the trigger. These can be replaced with 3D printed bushings if desired. The system requires a DC3 micro switch for the trigger and an 8x8mm normally closed (NC) push button, although the type of push button is unknown. The push button must be glued to a 3D printed trigger board. A small spring is also necessary for the two-stage trigger, measuring approximately 14mm in length, with an outside diameter of 6.5mm and an inside diameter of 5.5mm.
