MOSFETs give you contactless switching of any circuit. For AEGs, it is used for contact closure while the trigger is pressed.
Advantages in using a MOSFET:
- Contactless switching.
- No more damaging of trigger contacts by high current - used for signal only.
- Increases rate of fire as well as battery life.
- Works with all commonly used batteries (Ni-Mh/Ni-Cd/Li-Po/Li-Ion/Li-Fe) with voltage 6,6V-11,1V.
- Designed primarily for all AEGs - automatic electric guns.

Jefftron Leviathan Bluetooth MOSFET

The Jefftron Leviathan series is a processor-controlled MOSFET with Bluetooth communication. It adds new shooting modes, controls rate of fire, enables pre-cocking for DMR builds, active braking to give you no overspin on the motor, low battery indication to prevent you from damagin your LiPos, statistics... everything is controlled via application on a smartphone (iOS and Android). The device is fully integrated inside the gearbox instead of the original trigger contacts. Comes with completely made wires to stock or handguard, with 30A mini fuse and dean T connector, as well as a custom trigger on the V2 version and the best part is,  no soldering needed!

There is currently a JeffTron Leviathan for the Version 2 gearbox to fit the M4 (trigger included), MP5, G3 and more and they have now released the long awaited JeffTron Leviathan for ASG Scorpion Evo which replaces the original trigger board with a much higher quality and better performing module.
