Warren Hein Posted February 21, 2015 Report Share Posted February 21, 2015 I purchased a paddle switch to replace the original switch on my late 80's Unisaw but have a question about the wiring setup. Here's the current switch: It has three wires going to the switch plus a ground to the box. When I took a continuity meter to the three wires on the switch, there's continuity across any combination, regardless of the switch operation. The saw was unplugged at the time but I had not removed the switch. Here's the replacement: Continuity makes sense on this switch. With continuity from left to right only if the switch is on. How do I wire up the replacement? Sent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tpt life Posted February 21, 2015 Report Share Posted February 21, 2015 Don't measure continuity across the wires to figure switch paths. Measure across the pins of the switch with no wires hooked up. Just make sure you keep those photos safe:-) Quote Link to comment Share on other sites More sharing options...
Warren Hein Posted February 21, 2015 Author Report Share Posted February 21, 2015 I thought about that, but I still need to figure out what to do with three wires into four terminals. Should I bridge the upper and lower right terminals and connect the return wire (color?) to the bridge? This is a 220v circuit.

Warren Hein Posted February 21, 2015 Author Report Share Posted February 21, 2015 I just confirmed that the original switch is magnetic since the saw remained off after I tripped the breaker while the saw was running. I'm starting to think I'm better off rigging a paddle to the existing switch or replacing it with a similar magnetic switch with integrated paddle. Any ideas on a more suitable replacement?

tim0625 Posted February 21, 2015 Report Share Posted February 21, 2015 You need Fred....everyone knows a Fred or a Fred type. He's the industrial electrician at 'the mill' and he's forgotten more than we'll ever know about switches and such. Most everyone knows a Fred...call Fred.

Warren Hein Posted February 21, 2015 Author Report Share Posted February 21, 2015 Simpler solution. I just swapped out the cover plates using the new faceplate on the old switch. Gets the best of both worlds. Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
