I called my local Sears repair center yesterday and was told they can get a manual for the table in question. I was also told the safety switch is the same on all Sears router table models. I had a Sears router table that I tore down and used the safety switch on my self made router table, but the way I mounted it I can't see the part number. I do have the manual for it around here somewhere so I will look for it today.
When something is advertised as being foolproof there is always a better class of fool that comes along to prove them wrong.
