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.

Wrong switch, but good service
The switch came quickly. However was not the right one. I learned after the fact that there are about 8 versions of my Dewalt saw model, and I selected the wrong switch. That said, the return service was great and free.

Remove upper switch handle half. Note how the switch is wired. Remove switch from bottom handle half. Remove wires from the old switch and install them on the new switch. Assemble in reverse order.
Had to remove some plastic to make room for new switch. Used the continuity tester to figure out the differences in the switching between the original switch and the new switch. Was a $40 fix instead of a $400 replacement.
Took apart handle, took out the bad switch. Watched the YouTube video by Ereplacementparts. Re-routed a couple of wires, shortened one, reconnected wires to switch. Put back together. Back in business.
