Except Tony has it backwards; the switch is only the points and associated hardware, while the turnout is the whole thing. Operationally, one lines the switch. Like I always point out, it takes a whole track gang to line a turnout. :-)
Thanks, Dennis. Yes, I did get it backwards, should have checked. I had the track reference in the other room . . . entirely my error.
