I have never done that, though I don't see why it wouldn't work.  Since they have the reed switch option, one would think it would be very similar.  You might have to be aware of any common power supply ground connection, I haven't given it any more thought.

For those not familiar with the WeHonest product in question:

I don't have one but as GRJ says, the issue will be to understand the common ground issue between what the board "thinks" is ground relative to the outer-rail.  You would need to make some measurements on the board and/or take some really good close-up photos of both sides of the board to get advice on where to apply the isolated-rail trigger in lieu of the reed-switch.  This is made a lot simpler if the power to the logic board comes from an isolated/independent power supply as GRJ noted in his original post.

Or, if a fan of Rube Goldberg machines, I can imagine a scheme where the isolated-rail trigger powers an electro-magnet which then triggers the magnetic reed-switch.

For that suggestion, you must be related to ol' Rube.

If you're talking about the Atlas Snap-Relay, it isn't a good choice.  It has a similar coil design as the Atlas switch machines, park too long on the insulated section and you get some smoke and a melted Snap-Relay.

Never looked at the other one, no opinion on that one.

Thanks.  I have a lot of wiring for my 24' x 12' layout and have done some good stuff, but I've yet to tackle signals.  Finally trying to get my feet wet.  I know I will be fine  with Lionel Dwarfs 6-12883/MTH 30-11011s. I want to use them more as switch signals for 9 of my switches and ditch the hot incandescent bulbs, then use them as dwarfs elsewhere.  My o-72 switches have indication at the turnout, so I am good there.  As far as my track I need to figure out if the wehonest signals will work for me.  I run A/C 18v track power, so would need to switch it to DC with a rectifier and lower the voltage.  I see a lot on diodes as well.  I read a lot of forums and I see your comments all of the time.  Very helpful!
