Switch 391926-01

This Trigger switch has 2 terminals. This genuine DeWalt replacement part is sold individually. Switches are commonly replaced parts in tools. A switch handles on/off and variable speed operations. They also have a role in electric breaking; they can momentarily reverse electrical polarity. Because switches use mechanical internals, they will degrade and wear out over time, eventually needing replacement. Some common signs of a broken or failing switch are as follows: The tool has completely stopped functioning – it will not start. The tool operates intermittently, requiring multiple tries to turn on, until eventually it won’t start at all. The variable speed function and electric braking aren’t working properly.
