Tokyo Marui / Cybergun P90 Trigger Box

thingiverse

Replace the horrible "progressive" trigger mechanism in your Tokyo Marui knockoff with a tight, single-acting microswitch! This is a single, drop-in part that uses all the same fasteners and holes as the original switchbox. Trigger depth is adjustable. Uses standard DB1 lever microswitches to sense trigger pulls and the cutoff lever. To state the obvious: Do not try to power the motor through microswitches. This is ONLY for a MOSFET/SSR set up. Make sure you know what you're doing before wiring up the cutoff sensor, and understand that the poor design choices inherent to the gearbox will follow you into timing challenges down the line. I put a Teensy in mine to solve this by generating isolated and precisely timed firing pulses.
