I have been searching the web, but haven't found a relatively simple way of wiring up a scissors crossover for DCC (stock rail always the same polarity as outside rail with electrofrog) I am using ground throws and have attached one microswitch to each, but I have the feeling I will need at least 2 microswitches for geting the correct poarity to each part of the crossover..
Any ideas would be appreciated.
