I'm looking for advice on a dead table saw issue. This is a Delta Unisaw 36-812 10" tilting arbor table saw roughly 15 years old. The switch died today. It seems like the coil that pulls the relay shut has burned out. The on and off switches check out and the saw runs if I manually push in the relay. Does anyone know if components of the switch can be replaced or where I can get a replacement for the whole assembly? So far my searches have come up with a lot of back-ordered or out of stock results.
