Just jumping into this thread for the first time...
Regarding alternative toggle switch for F/T turnouts that would permit toggle position as an indicator of routing (for our friends who are sight-challenged, et al)... The other day I was going through a box of old (we're talking 60+ years ago) stuff and came upon some Walthers E201 toggle switches. How many of you remember those??? Well, they had multiple uses for turnout control, panel indicator lights, track signals, etc., etc..
But, pertinent to this discussion, they had a set of momentary contacts that could be used for a twin coil switch machine but were open circuit at the extremes of the toggle throw. Therefore, you could simply glance (or touch) the toggle position and know the routing of your turnout/track switch.
They're no longer made....VERY complicated assembly, and certainly old tech in comparison to today's more sophisticated electronics. Nonetheless, they hearken back to a day when they were innovative and rather fancy for the model railroader.
Now they show up from time-to-time on the internet auctions.....like d'Bay. Reasonably priced, too, since they're, as I said, 'old tech'........for us old pharts!
Seriously, though.....others remember the E201's????
