If what you say is true, how is that manufacturer's of power tools that
are easily converted from 110v to 220v are so converted by merely
switching the connection of a pair of leads in the machine? They
certainly are not switching both sides of the connection.


Actually, they areI can't speak for all tools and all manufacturers,
but both my Delta bandsaw switch and my Jet switch (which I bought to
use on my table saw--240V) are DPST switches, and in 120V use switch
both the hot and the neutral, and, with no further rewiring necessary,
will switch both hots of a 240V supply.

In fact, I can't think of a reason why a manufacturer of power tools
easily converted from 120V to 240V wouldn't do it that way.

Hmmm, perhaps my bad - I made an assumption and you know what...

I was thinking of the only such tool (other than an air compressor) that
I switched over to 220v being a Craftsman RAS (and yes, it was a 70's
vintage Craftsman that preceded many of the Crapsman power tools that
followedg).

I didn't think it had a DPST switch but now I'm curious enough to check
and see. As I mentioned, I think it's a good idea but wasn't sure that
it was required in that setting.

Thanks.
