I have a yard with 3 scratch built double slip switches that have insolated frogs on each side. I have no problem wiring the frogs for two of the possible routes but for the other two routes the polarity has to be reversed. An individual Tortis switch machine throws the 4 switch points on each side. The single pole double throw contact points on the switch machine currently control one frog. The second set of contact points control the layout tract board route lights.
I may be contacted by phone at 203-226-2798 or email at wsptmdlwks.com
Thank you in advanced
