The relays I use have 5 amp contacts, more Tortoise machines than you could ever want to hook to one control action…

I thought I should update what I decided to do. The mention of the NCE SwitchIt by MaxMan led me to check them out which then led to me watching Larry Puckett, the DCC Guy, and his video on the NCE Switch8 Mk2. This what I decided to go with. I realize it is more expensive than several of the other solutions proposed, but it is easy for me to understand, easy to work with, and versatile. I ordered the Switch8 Mk2 and the Button Board. I also ordered the NCE push buttons. When they arrived, I mounted them on some plywood and added terminal blocks so I can avoid fiddling with the small green terminals on the cards once I am under the layout.
I have been able to easily setup and test changing Tortoise machines from two push buttons from two different control panels. It was also easy to test the Tortoise machines on a crossover. Wiring the LEDs on the panel was a breeze thanks to Puckett’s helpful video series on Control Panels.
I was only going to use this system to control the turnouts on my peninsula, but now I think I will be using them elsewhere on my layout. It is also neat that I can control the turnouts from my computer, not something I had originally planned on doing, but an interesting feature I might take advantage of later on.
Thanks everyone for your help and suggestions.
