Slow tortoise here . . . . 
Many thanks to all of you very patient folks walking me through the nether world of electronics. I am beginning to understand this and I hope that is a good thing. 
1) Now I understand that to use the DCS AIU to throw my Tortoise switch machines I will need a latched relay 
(I assume one per switch) and that idea is not going to fly. I will throw the Tortoise machines with SPDT switches. So . . . . .
Are there SPDT switches that light with red and green depending on the curved route or straight route when I throw the switch? If so, can someone please point me to nice SPDT switches that will look good on the fascia of my layout or on some kind of switch control panel? Can you please tell me where to buy these things? When I look online there are confusing "ratings" for these things and I would like to save time and aggravation. 
2) The New Munoz Lines Will be an island type layout with an "inner" steam yard requiring a duck under for access 
(another long story for another time !) and I will want to place the SPDT switches in the yard area not on the outside of the layout so, I guess, I will end up with more than one panel of SPDT switches depending on where on the layout the turnouts are located. So . . . . .
Can someone suggest how I might design these individual switch control panels in/on which I will mount these SPDT switches? For example, here is a switch that looks like it has red/green and a little box panel that seems like it would work OK. I do not need to have the track diagram on the panel as that seems a bit complex. I dunno, is there a better way to do this?
3) For my sidings, I would like switches that turn the power on off. I need switches that simply light = on and no light = off. Suggestions? Perhaps I can buy all of these switches in one place . . ?
The slow tortoise is actually learning with all of your help and I do appreciate your patience. It is somewhat embarrassing to keep asking these question that seem pretty basic. Many thanks !!
PS: Mike, you e-mail did not work. Can you hit me with an e-mail?
