The Systema Switch Device is a transister relay device that helps regulate voltage to your electric motor while protecting the more delicate trigger switch assembly from overheat or burnout scenarios.  The use of this device allows precise power regulation to the motor, increasing trigger response and battery life.  It uses two mosfets which store battery energy until needed, and routes the power to your motor when you pull the trigger!  This is an excellent addition to any AEG or upgraded airsoft electric gun.The Switch Device require rewiring of your gearbox as well as soldering wire attachments.  We recommend this upgrade to advanced users.  Please feel free to consult us if you have any questions about the Systema Switch Device prior to installation.  We are not responsible for any damage to the Switch Device as a result of improper wiring or reversed circuit polarity.  Please ensure you thoroughly read and understand the installation instructions prior to installation.
