Electronic Module and Switch Assembly
The TE 6-A22 utilizes a brushless motor where the trigger serves as a potentiometer signaling the control board. Ingress of conductive concrete dust or mechanical fatigue of the sliding contacts leads to signal drop-out, manifesting as a 'dead' trigger. Because the switch is electronically tethered to the motor controller for heat dissipation and logic, the entire module is the required replacement to restore reliable communication between the battery and the brushless stator.
