What I got was a package from Gardner of Colombus Ohio containing
an opened plastic bag labelled PN 664106001, which is the PN for the
BT3100's complete switch assembly. Except that the bag didn't contain
anything except diagram #114--the BT3100's rear switch cover--and 3 screws.
Assuming I can get them to send me a complete switch, will a BT3100
power switch fit into the BT3000 hole, and not bump into
the older electrical box?
Maybe I'll just tell the buyer to get the Sears switch. I now recall how
annoying I found the right-side switch waaay back in 1992. I believe
I solved the location problem to my satisfaction at the time
by just moving the sliding miter table to the right side of the saw
and doing most of my work from there. I understand that wouldn't
have helped the faulty switch problem, though.
