that doesnt sound good, I had a dusted up switch one time, the tool just totally quit.. checked motor,bypassed switch and motor ran...then took switch apart, cleaned fine saw dust out of switch and it worked..your problem sounds more terminal. Hope its not. I bought a 4x132 sander last week from a guy just west of you near Middleburg. if you need it, I have a 6x48 Craftsman sander you can borrow..
