Switch 394375-04

This is a genuine Dewalt replacement part and is sold individually. Switches are commonly replaced parts in power tools. A switch handles the on/off and variable speed functions. 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 requiring replacement. Some common signs of a broken or failing switch are: • The tool has completely stopped functioning • It will not turn on. • The tool operates intermittently, requiring multiple tries to turn on, until eventually it won't turn on at all.
