Edward, I’m like you, I have never used a foot switch because of the way I sit. The DeWALT switch is not sealed. Dust gets into it and fouls up the contacts. Like was mentioned, most folks use a foot switch, but for you and me, we have to deal with the switch. You will not find the switch at the Hardware store or any store. you will have to order it from DeWALT or wherever you order parts from. That being said, I have always repaired my switch’s. If you are a handy kind of guy, you can do it too. Let me know what you want to do, and I’ll walk you through it.
