Thanks Jeff! That did it. I'm still wondering about the red wires,
though. One appears to be the neutral from the plug, the other
appears to be the neutral to the motor. It makes sense that they're
connected to one another, of course, but what (in the switch) would
they be connected *to*?

I think it's just a tie point (an unused pole of the switch). They
need to buy mostly DPST switches anyway for their domestic market and
the Euro market, so they probably wouldn't bother saving a couple of
pennies by sourcing a SPST switch just for US/Canada if they can put
the unused spade to some use. ;-)


But since in the US with 110V, you don't know which is neutral and which is
live and with 220V you have two lives, surely all your devices should have DP
switches???


It should have a polarized plug, or a three wire plug. Both only plug
in one way. Also, all that is required is to switch the line, so a SPST
is all that is required.
