Depending on the orientation of the assembly of two switch tracks, be sure to keep the insulating pins in their proper rail.

In other words, keep the insulating pins in their respective positions, no matter how you arrange the switch tracks.  

You may find that when the switch tracks are in the positions shown in my sketch, that extra track power feeders may be required.

It only takes a quick link to the rail of regular track outers to test which rails need pins on anti derails.  (Jump power to plug or center rail, no other connections or assembly. The rails that work it get pins. This covers all the motorized switch points I believe; O, 0-27, some Super O (some S-O have contact ears/tabs that form a flexing wedge and hit the backside of wheels)

You can extend the sensing cabability with isolated rails beyond a switch too. Useful if you use track power and lower volt engines as it gives them more time to react)
