Some switches use Com/no/nc labels stamped real small right by the terminals Common, normally open(off), normally closed(on) for spst.
For a 2 position ike ike though, some use a #1 & #2 and skip labeling the common at all ("like that"..... spellwreck insists on ike ike and it gets worse if I try to change it)
Also, I'm not sure how/if Atlas has an anti-derail feature; but it's discussion is conspicuously missing above.
. Lionel track would use another plastic isolator at each turnout exit on one of the outside rails. That little rail is a trigger, any wheels/axles on those provide a "ground" to the isolated little rail and that is in turn connected to the turnout coil motor (hot always on) so it auto-throws it if points don't already point to the oncoming wheels. You might not even have the option, but that is likely why you thought you needed more plastic clips.(and might yet,? You can also make a circuit like this on plain (isolated outside rails) track to add auto-anti-derail to most turnouts if not equiped) (most brand tracks can be modded to have isolated outside rails, and you can often shorten the part that triggers too. (so you don't pak on it, etc)
