Switches are commonly replaced parts in power tools. A switch handles all 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 tend to degrade and wear out over time, eventually requiring replacement.
Trigger Type Switch Compatibility:

NOTE: 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
- The variable speed function and electric braking aren't working properly
