Just ran across this post. Great job Rod! I also adopted Dale H.'s capacitance throw philosophy and use it to throw my Atlas switches. Since I use Arduino control for the trigger source I needed to devise an interface arrangement that worked for my layout. Our capacitor boards are eerily similar. The other board is a distribution board that interfaces between the Arduino and the cheap relay boards with opto-isolators available on eBay. I use the 4 pin header bridge to connect the distribution board to the relay board and 20awg bare copper to form a buss between the relay board and the capacitor board with a 2.2 ohm resistor to the common pole on the relays (prevents sticking contacts). Glad you've gotten things to work for you.
