    I was ‘triggered’
    Saved me from having to buy a new saw, the only negative was the new wiring diagram since the shortest wire has to go the farthest distance to attach to the proper terminal. Might want to research that guys.

    Right Replacement, perfect fit.
    This was the perfect replacement part for my dewalt circular saw. I've bought several parts in the past with this company hands down my go to parts store. Great price and fast shipping. I highly recommend doing business with them.

    Fits OLD Black and Decker U337!!
    I have an old Black and Decker U337 saw my father-in-law picked up for me at a garage sale. It worked well, except the switch was intermittent. Took it apart and found the contacts nearly eroded away. Searching for a switch for this saw kept pointing me to this DeWalt part. I was skeptical, but as time wore on, I saw I was never going to get to "rebuilding that switch." I decided to buy one of these, as the mounting and size looked correct (thanks for the great part pictures, by the way!!). Turns out it was a perfect fit. I had to wire it differently as this saw doesn't even know what a blade brake is, and I added a little heat shrink to the wire terminals since they had a lot of exposed conductor and the new wiring had them much closer to the case and to each other. But the switch bolted right to the saw, fits perfectly, and works. No more saw stopping in the middle of a cut, or having to double-click to get it to start!
