Switch and Module Assembly
The trigger mechanism is vulnerable to high-velocity dust ingress which physically obstructs the travel of the plunger and degrades the internal return spring efficiency. In brushless models like the DCF887, the trigger is a non-serviceable part of a larger electronic module that manages power delivery. Replacing this assembly restores both the mechanical spring-back action and the electrical signal integrity for variable speed control.
