21 views and nothing, please people i'm desperate to know if i can use these for something.
Mark,
To start with, welcome to the Gauge. Someone here probably has your answer, but it could be that the first 21 to view your post may not be among them or they could be "guests" who cannot post unless they register. I'm not sure what you are calling a "passing contact switch", but I have a feeling it's a switch that will allow you to throw more than one turnout at a time. On the other hand, if you had posted a picture or a description of what you have there, I, or someone else might have known better if that's what you're talking about.
In any event, there's nothing in modeling that is so "desparate" that you can't wait more than two hours for a good answer, so hang tight, help will show up.
In the meantime, I did a search here on, 'passing contact switch' and got a couple of threads that might have information you can use.
