Barb, the switches on the Triton routers have, and I guess still are a problem spot on their long term life. You can Search just
Triton router power switch, and get reads about both the 2 1/2 and 3 1/4 units, and it seems there is huge agreement that they aren't a very good, or dependable switch. I have one of each, and have been lucky I guess, no problems.
I would ask Triton as you already have, and see if they are standing behind the product. An assortment of "fixes" will be noted if you do read the accounts on many forums, Most don't sound like they have anything to do with a bad electrical circuit. Things like whacking it real hard 3 times, stuff like that.
On my main router table I upgraded a while back to a Bora 3HP, and it's a tank. I just have the Tritons as hand held now, so hopefully if they do act up, I'll just need to put the bit into another router, and keep going.
