Description:
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.
  • Products Compatibility

    This item works with the following types of products:

    • • Chop Saw
    • • Grinder
    • • Sander
    • • Saw
