S Gauge Switches

I am interested in knowing what kind of switches are available in S gauge, also
how to wire an older American Flyer remote control switch with four screw terminals. Is there a way to insulate the rails so I can run a siding on its own?
My switches have a small switch built in that says two train or regular, what does this do far as wiring is concerned?

The terminals from the switch housing goes black, red, yellow, and green. The black is base, yellow for the switch indicator light, red to go to the spur and green to go to the main line. The other lttle switch is “2 train operation” (away from housing) and “regular operation”(twards the housing) What it does is in regular operation position power is on both the mail line and the spur. In 2 train operation, power is only on the line that the switch is aligned to.

This is the best site I have found for what’s available in S - http://www.trainweb.org/crocon/sscale.html it covers American Flyer, scale, and narrow gauge.

I want to thank you for the info on wiring the older AF switch, I bought the switch at a train
show in south Florida area recently.

Did the controller come with them?

Did not get the original switch control with the switch, am using an 022 Lionel
control with the S-gauge switch.
Also what voltage is best for the switch?
I have found that the switch works good with ten volts AC from a small Lionel transformer.
