Switch and Module Assembly
The internal potentiometer/rheostat within the trigger housing has developed dead spots or carbon tracking failures. This prevents the motor controller from receiving a consistent PWM signal at specific trigger depths, leading to intermittent power delivery. Replacing the integrated switch and PCB module restores the integrity of the speed-control signal path.
