DPDT Switch

[mdn7]

I want to install a programming track/siding into my DCC layout, have done some research but there are dozens of them out there. So Could someone kindly point me in the direction of a DPDT 3 way switch for the programming track. I am sure someone can recommend a good,reliable, switch.. TIA

If you follow the link and scroll down to Programming Track, there's a couple of schematic diagrams for this. The 3rd option seems the best solution.
