Re: Double pole switch of Single pole?

Based on advice from others, I have used a double throw. Don't forget you need an isolating section before the programming track, that has power turned off when you have the programming track on. This prevents a loco from connecting the programming track to the other tracks, which would fry the DCC.
I used this circuit.

I have wired a decoder to the motor on the turntable. It has an assigned address and I control it like it were a locomotive. The decoder/turntable is wired directly to the wiring harness that the roundhouse complex is wired to. I would like to make roundhouse track a programming track. To keep from programming the turntable decoder would I have disconnect both wires using a double pole or could just disconnect one wire using single pole switch?
