The file 'Airsoft V3 Cutoff Switch Holder 3D Printer Model' is (stl,step) file type, size is 104.3KB.
Update: added extenders that can be added to the cutoff lever with glue to provide more surface area to press the switch evenly.
Genuine Omron D2F-FL2-D3 microswitch recommended. It has a low operating force (longer cycle life), metal arm, solder terminals. It'll last longer than clone switches. 12-13mm 2mm (preferably stainless) rods are also required for fitment.
Solder to C and NC (normally closed).
If a low operating force switch is not used, a more powerful spring may be required for the cutoff lever. 3.5x12mm (0.5mm wire diam).
Designed to fit LCT V3 gearbox to work with Perun ETU++, providing information to the mosfet allowing semi automatic fire. This is for bullpup configurations as there is no room for a trigger on the gearbox.
