I had tried to scan and post the Tortoise wiring instructions but it was too dim to be legible so I trashed it.
I use single throw on/off for "through" or "out"[mainline or siding]. When I built my existing small 9x16 layout I discontinued using the 7 ASCs that controlled my 32 turnouts from the handheld remote on a former larger layout. Straightforward and simple now- 17 tortoise, a majority in the Service Yard,powered by a 12 VDC wall wart. As you can see on the schematic, the "lean" of the toggle handle tells me at a glance the turnout's position---main or siding.
