I have a Delta Unisaw 34-761. The power switch is the pushbutton switch side by side with a thermal protector (Klixon 09 T7C BET44DA-2). The terminals on the thermal protector were soldered poorly by some previous owner and I cannot get solder to join with the nubs that remain. I cannot find a replacement.
I freely admit that I am not clear on "Magnetic Switch" vs "Starter". I hold down the green button to start the saw - If I release too early, it will not stay on. Motor is a Rockwell 83-621. 1.5HP wired for 220v, 9.6a. When I got the saw at auction, the cord was removed. I checked the wiring, and it was per diagram for 220v, I replaced the cord and it worked fine. I did notice that the wires in the switch box were in poor condition - frayed, electrical tape falling off, some conductors at the back of the thermal protector were broken. I decided to replace them. They appear to be originally crimped.
I like the Grizzly H8242 (http://www.grizzly.com/products/220V-Magnetic-Paddle-On-Off-Switch/H8242)style switch but I don't think it has thermal protection.
This (http://www.grizzly.com/products/Magnetic-Switch-3-Phase-220V-Only-5-HP-15-20A/T24104)seems more correct, but I wish it had the paddle shut off. (Grizzly T24104 if I did the link correctly)
My first choice is to just replace the thermal protector. I emailed Klixon to see if they offer one but have not heard back and can't find a cross on their web site.
Second choice is to get a paddle mag switch. Do I need to add a thermal (I think so for motor safety)? Is there an obvious choice to buy?
Or - just get the Mag switch with thermal and normal push-buttons?
This is the back of the switch plate. Red wire was connected to a wire on the protector. It broke off. Crimp nubs on the protector will not take solder. No sawdust for me until this is fixed......:mad:
