<p>I'm trying to reduce the number of wires running under my planned HO DCC layout. I thought I would control 13 snap switches traditionally with spst switches on a schematic. Still like this idea...but would involve minumum of 27 wires back to the control area. </p><p>Not clear on how function decoders work for DCC switch machines. </p><p>1. I can power them from the track...with a resistor in line ???</p><p>2. What is the best brand decoder for this???...perhaps one with most "hookups" for switches?</p><p>3. How many wires, then, need to be run back to the controller?...none? Do I just programme the switches with the DCC decoder?</p><p>4. How complicated is the operation of the switches when programed....do I need to have a list of the switches and then "key" the id in whenever I want to switch? </p><p>Thanks </p>
