Side note: The original switch contacts were welded closed, not allowing the saw to stop. I was able to redress the contacts and put the switch back together. I swapped out the new for the old and have been using it ever since. The new switch is saved as a spare.

Epic Version:
This was a technically simple but physically awkward repair to a part that should not normally need replacement.The poor kid who broke the switch was tearfully honest and apologetic and if she hadn't told me what happened I would never have discovered who was responsible, so, yeah, there are still great kids out there.
First, disconnect the power before working on any machine.
To replace the broken switch it is necessary to remove the cover plate on the bottom of the control housing. Unfortunately, the legs and mounting surface of the stamped sheetmetal stand on the model JWDS 1632 drum sander are angled for stability. Without removing the stand I could not get a straight shot at two of the screws that secured the cover plate. So I angled the screwdriver. The screws came out easily enough, but I chowdered the heads in the process.
Once the cover plate is off, the circuit board can be pulled out of the way so you can reach up underneath the control panel with your favorite spudger to release the spring tabs that secure the switch. I have a couple of old butter knives ground and bent into various shapes for this purpose.
I found that the best approach was to wiggle the switch housing back and forth, pushing alternately on each end of the housing as I released the spring tabs a bit at a time on each end. Eventually the switch comes free and you can pull it up out of the housing. Allow the circuit board to come up with it and there is just enough slack in the wires to remove them from the old switch and replace them on the new one, one at a time.
Push the new switch back into the face of the control panel. It will sort of click-click-click, and then snap into place. Push the circuit board back into the housing and then reinstall the coverplate, securing it with the screws. Take care to NOT cross thread the screws, which I did because of the way the stand interfered with the shaft of the screwdriver and because I was working over my head while crawling around under the machine, and because I was too lazy to just take the machine off of it's stand in the first place.
Test the machine to make sure the new switch works. Then, sulk for a few days because you cross threaded the screws and chowdered their heads up and made a carefully maintained machine look like it was chewed on by a dull beaver. Go to the local hardware store and pick up four (M6 I think, but you better check) socket head screws and washers. Remove the chowdered up old screws, chase the threads with a tap, and replace them with the socket heads because you can remove and install them with a BALL DRIVER next time. Hopefully there will not be a next time.
