I have a 20 in h DeWalt not sure type 1 or 2, it won't start,checked the switch,it's got power there and clean,could it be brushes

Dewalts are known for flaky switches.  Fine sawdust gets in and fouls the contacts.  Take the switch cover off and blow the sawdust out as thoroughly as possible.  See if that solves your problem.  If it does, I suggest getting a footswitch, which will help keep the problem from recurring.

Hi George, Welcome to the Village!

Back in the day when I was using a DeWalt saw I had same thing and as Bill said.. check the switch. For me back in the day I could blow the switch out but it eventually got to the point where that didn't work either so I had to buy a new switch and I always did use a foot switch but that doesn't stop dust getting into that switch. What I found to work great for me was to cut up a old rubber / latex glove and place it over the power switch then I used painters tape and taped / sealed up around the switch. Never had another issue with it for another 6 years until I sold it to a friend.. and I believe it is still going strong.

I had the same problem.  I ended up replacing the switch.  An easy fix.
