Use caution, I am not a technician. This is just how I did it.
My saw has been great but unexpectedly only powered on while the on button was held in. The off switch was not stuck and the motor seemed fine. I usually feel a slight click when the magnetic switch latched and this click was absent. The switch is Delta part # DPEC005673 – SWITCH. It is #97 on 36-725T2 parts list diagram. The switch itself, although held together by pressure tabs, does not appear to be repairable. I removed the switch bracket (which doubles as the back of the switch case) and looked for any signs such as burning or bad smell and there was none. I contacted delta by email and promptly recieved a reply. After supplying an image of the original receipt, an image of the data-name-plate on the lower leg tubing and an image of the broken part, the replacement was on it’s way. I received it in 3 days, Thank you Delta Machinery. I am not a technician and take no responsibility for this information.

Their email requested;
1. Copy proof of purchase
2. Model/Catalog and Equipment serial number from nameplate
3. Complete name and address
4. Description/picture of broken/damaged part (s).

DISCONNECT POWER FROM WALL OUTLET….....DISCONNECT POWER FROM WALL OUTLET….....

The process is mostly easy but one tip would have saved me a little time and prying, the switch comes out the front of the case after pulling off the white tabs on the back side. Did I mention to unplug the saw from the outlet.

.
.
Remove the 2 bolts holding the switch bracket to the saw.

.
.
.

Remove the 4 corner screws holding the bracket to the back of the switch, the mounting bracket doubles as the back wall of the case.

.
.
.

Remember where the 4 spade connectors go, these are female spade connectors, pull straight back to get them off. Be gentle, the switches male spades are a bit flexible as I used pliers to close the female spade gaps a little to tighten their connection. Do not close the gap all the way, you will not be able to get them on. You do not need to remove any further connections, the switch case is now free to be carried to a bench.

.

The switch is locked in by white tabs. You could probably squeeze them together and push the switch forward but that did not work well in such a small area. The switch comes out the front after removing those 2 tabs by prying them out. That tool is an awl placed into the small hole in the tab. The new switch has the tabs pre installed, don’t touch them, leave them where they are, they will slide through from the front.

.
.
.

Now is a good time to take a soft brush and clean out the switch case. Make sure the new gasket is on the new switch. When installing the switch, the green button is closest to the hinge. The new switch goes in from the front, press straight down until you hear both tabs lock in. The new switch includes the see-thru rubber dust protectors, the tabs (don’t touch them) and the gasket.

.
.
.

Reverse the process, Be careful putting spade connectors back on, the switches male spade connectors will bend if the female spade connectors are tight. Put the wires spade connectors back on the new switch. Re-install the 4 Screws and nuts holding the bracket to the back of the switch case, then bolt the switch bracket back on the saw.

P.S. Don’t you dare keep that old switch, you got enough junk lying around !!!!

UPDATE Magnetic switch was the problem everything now works…

Looks like you did a great job. You must feel proud when you power up your saw.

You said you had to supply the original receipt and proof of purchase.

What if you bought it second hand or lost the receipt would you still be able to get the part from them or would you have to buy it from parts resellers?

No.

From their site;

””WARRANTY PERIOD. All warranty claims must be submitted by the original purchaser during the following period from the date of retail purchase””.

However, the part is only 17 dollars.

Like you I’m no technician let alone a sparkie… and get a buzz when I manage to repair successfully without hospitalisation…

I started typing out an alternative option as I have a hate relationship with these type of electrical mag-switches and as I was typing, I remembered my soapbox stance about peoples recommendations contravening safe practices. Having realised that mag-switches are advertised as an added safety measure, I’ll leave my comment to ”well done”.
