Ripping face frame stock last night and the tablesaw wouldn’t shut off. Had to pull the plug on it. Took the switch apart, blew it out and put it back together. Saw operated normally for 3 or 4 cycles and then would not shut off again.

Saw is a Delta contractor 36-650, 115 v, 1 1/2 hp, toggle switch. Should I hunt down a OEM Delta replacement switch or just get a magnetic switch from some online retailer to repair the problem. The saw is discontinued and I cannot seem to find parts on Delta’s site. I’m not much of an electrical guy, how hard would it be to retrofit something else?

Check at Grizzly.com. They should have something to replace that switch.

If you search for the part number (438010170206S), you will find them all over the place, some a bit cheaper than that one from ereplacements (like here). And in many instances, if you get the actual switch part number off the switch itself, you can find them significantly cheaper. But since you are planning on replacing it anyway, it wouldn’t hurt to open it up and see if it can be fixed first. They are usually pretty easy to open up.

I am fixing up an old saw that has some cuts in the power cable insulation and a switch with no safety features mounted on the cabinet where it is not terribly easy to reach.

I’m going to retrofit with a pair of $16, 220v switches with big OFF paddles that I ordered on Amazon. The second switch is for a router wing. They will be mounted in easy to reach spots which means electric boxes (extra deep), mounting brackets and cable clamps to do it right.

I read the safety argument for a magnetic switch but decided against it due to cost. I will just hit the OFF paddle before plugging in and after blowing a breaker. If I used it more often or expected other people to use it, I would go magnetic but I feel OK about cheaping out.

I don’t expect this to be a terribly difficult project but it will take some time.

Magnetic paddle switches are available for about the same price… like this one or this dual voltage one for even cheaper. Lots of other ones out there as well.

I got the Woodstock D4151 which seems identical.

I was thinking the cheaper switch was a copycat or mislabeled because it has less reviews on Amazon.

So maybe both are magnetic? Maybe neither?

Either way I doubt I wasted $6.00 and missed out on a magnetic switch at the same time.

I think there were a couple magnetic switches in the $40+ range made by Rockler or someone. I didn’t want to spend that much.

They should do the job.

I don’t think the 4151 is a mag switch as it would say so if it were. That is the same switch as the one Grizzly is selling. The two I linked two are definitely mag switches though.

I think there were a couple magnetic switches in the $40+ range made by Rockler or someone. I didn t want to spend that much.

Those were most likely IEC type switches (starters) that include overload protection as well. They are actually a step up from those magnetic paddle switches, as they have bigger contact points and will last a bit longer. The only problem with them is that once a component goes (contact points, control voltage coil, etc..), you have to replace the whole thing. A top tier NEMA starter has significantly larger contacts and the individual components can be replaced as needed, but would be way overkill for the machines being discussed.

Brad
