Two switches with one switch controller

Not really - looks like you are on the right track (no pun); just use an adequate transformer for aux power - most will do.

I'm assuming that you know that both switches function normally, individually. 

I am not familiar with the switches you have, but I don't see why it wouldn't work as you want them to?

I have 4 pairs of Atlas switches wired that way. Each pair is operating from their own single controller and they work just fine. It's been a while, but I believe I had to swap some of the directional wires at the switch to get them both to go the proper direction. On some of them one switch needs to be set to straight and the other needs to be set to the curve.

Try utilizing Atlas  snap relay.

If you are using the K-line (and not K-Line by Lionel) I think this owner's manual may help you.

Another benefit of FasTrack Command Control switches. Just program them the same switch number.

I believe this phenomenon is caused by a sneak path through the controller light. If you remove the bulb in the controller or wire the bulb directly from the transformer you will be able to wire the 2 switched in parallel with each other.

Of coarse if you rip out the O27 track and switched and convert to O then this problem goes away for good.

AREIZMAN suggestion might just be the trick. One other thing to consider, are the switches pulling track power from the same transformer? If not, I wonder if the transformers could be out of phase and contributing to the problem.

One transformer in this case.

Thanks. I read through the instruction manual and couldn't find anything to address my problem. I think one of the posters below may have nailed the problem.

 Just wondering if an Insulated pin( Joint) used for the non-derailing feature has let go..   You do have insulated pins?

TM Terry,

   Absolutely correct sir and it works like a million bucks every time.

FasTrack Commmand Control Switches run from the Cab2, ya got to love it.

I think so, but I will doublecheck the connections over the weekend. Thanks for the suggestion.

I duplicated your set up tonight... track power, one controller, all bulbs in place. I cannot duplicate the problem.

Thanks Rob. I'm going to try again today. I agree it should work.

Are you using these bulb-type switches or the LED/motor driven type?

Problem solved (sort of). The 2nd switch doesn't work period. I connected it to it's own controller and got the same inaction. Pulled the cover plate off and saw some obvious home repairs by the prior owner.  It's going to take some tinkering, perhaps by someone more knowledgeable with switch mechanisms by me.

Got two other sets working. Just happened to be dumb enough not to test the switches before installing them in the layout. Won't make that mistake a second time.
