Looking for recommendations for a paddle switch that will work on my 1990 Unisaw. I replaced the cord when I got the saw a few years ago, everything seemed to be original. I would like to order a paddle switch and have it here before I take the old one apart. The switch is now in a metal box connected by conduit to the underside of the cast-iron top. A lot of options popped up when I searched for one, hoping someone can save me time researching.
