I assume you have answered your own question -- if you haven't: Klixon is a product brand name of thermal overloads -- you'll find one on your clothes dryer exhaust and other similar equipment -- it has become somewhat of a generic name like "Levi's" did in the late 60's or like "Coke" did in the early 80's (and why they changed their product names a little to protect the "brand" name)
