I made my own terminal blocks so I could run my switches off aux power. I used two of the "neutral bars" like you would find in your home electric panel. (5$ for a 24 spot bar at Lowes) I plan to do the same with my track power. I am adding DCS shortly and all the wiring diagrams I've seen shows using the MTH blocks that look like they are on a circuit board.
Is there any specific reason that the MTH terminal blocks would be better? Do they have any resistors or any other type of added circuitry that smooths out the DCS signal, or cleans it up?
