JeffTron Switch Brake V2

Switch Brake V2 by JeffTron
This is a special MOSFET module designed for V2 gearboxes using a micro-switch instead of traditional trigger contacts. The switch brake completely replaces the original micro-switch in the gearbox (requires soldering). It features active motor braking, which stops the piston in its resting position after each shot. This prevents partial spring tension, increasing the lifespan of internal parts and the spring itself. The unit also fixes the issue of double shots in SEMI mode with high RoF setups. Installing this module boosts rate of fire and extends battery life by reducing energy loss through a more efficient power transfer than traditional wiring.

Key Features

Active motor braking uses residual motor energy for stopping
No trigger contact wear, no current draw in standby
Protects and extends the lifespan of gearbox components
Stronger effect with neodymium magnet motors
