4 xing wiring

Wiring a crossing with one dpdt switch or Reversing module

The north frog and the south frog do NOT need to be gapped. Only west and east .

Hook the two wires from the main to the N and S
Hook the W and E to the reverser output That's it.
If you want to use a toggle switch:
If the above is the case then the hookup is like this:
on the back of the dpdt are six solder lugs.
there are two wires from the main rails and two from the siding
rails. So we have w-m and e-m from the main and n-s and s-s
from the siding (east mainrail, west mainrail, north sid, south sid)
ok here is the back of the switch.

             n-s |   | s-s  
    westfrog  |   | east frog         
           w-m |   | e-m

Is that clear??  I hope that wasn't too confusing.The north siding rail and the south siding rail hook to the toptwo lugs.
The west frog and east frog hook to the center lugs
and the west main and east main rails hook to the bottom two.
The north frog and south frog are powered by the main 
rails since they don't have to be gapped. 
You may want to gap after the crossing to separate the siding as a separate block 
but that only needs one gap after the south frog.
That should do it. If I've made something confusing, let me know and I'll try to clarify it.Have fun....-Stephen Hatch WTA

Wiring 4 crossings with one DPDT switch

First locate the 4crossing and glue it in place using Epoxy glue.Smear the glue all over the bottom of the rails. Press it in place. Put some weightson the 4xing until the glue cures (24 hours)
Then (using a dremel with a cut off disk) cut the gaps as indicatedin the drawing.
Not all rails are cut both sides so be sure you just cutthe rails as indicated.

The back of the dpdt switch is wired criss-cross with the positive andnegative wires. These positive and negative wires are hooked up(in addition to the criss-cross on the switch) to the 4 positive and 4 negative places on the 4crossings. Then the 4-A's are hooked tothe A position on the switch and the 4-B's are hooked to the B positionon the switch.

This makes the crossings work as east-west or throw the switch andthe crossings work as north south.

Let me know if you have questions.
Is the diagram clear enough?
