I have about 20 Atlas switches on my layout. Currently they are powered by the 14 VAC terminal on my Z4000 transformer. When I turn on all the building/accessory lights, the switches operate somewhat sluggishly as apparently there is too much for the transformer to handle. This is even though only one switch at a time is operated! (Atlas recommends 18 volts for these switches) I notice that Lowes/Home Depot as well as others sell a 16 Volt Ac Transformer. If I change the wiring so that only the switches get power from the "door bell" transformer (which is what these 16 volt AC transformers are used for) will this work? Just curious if anyone has tried this yet, and if so, with what result. Thanks

Should be no problem. When I first ran the Christmas layout down the halls to my son's room, I used a 16v AC wall pack plugged in down there to power just the K-276 switch for the return loop. I have since run cabling under the floors through the basement to get train & switch power to the other room.
I use a landscape transformer to power my Atlas switches. I plug it in my power strip and the wiring terminals are enclosed. I suggest that you consider the use of one. If you are electrically adept you could use what I assume is a doorbell transformer you reference which would need wiring in an electrical box power pulled from somewhere.
Gentlemen,
Got to say I ran all my old 711 and 072 Lionel switches off an an old ZW, increased or decreased the power requirements as require with the handles and you get 4 tracks to use with the old ZW, even the 250 ZW worked great, I did prefer the 350 however, I had a lot of switches.

The "Nutone bell transformer arrived! I checked the output voltage, which is supposed to be 16 volts AC. It is not. I measured 18.7 volts AC with my Fluke meter. (No load on the output terminals....as the Atlas switches would only provide a load, when activated to throw the switch) Is this too much for the Atlas switch coils? What do I need to get the voltage closer to 16 volts? I don't want to harm the Atlas coils. Thanks.
Contact Atlas to verify it can take the extra .75v., but more than likely it is fine.
And /or throw a bright 14-24v bulb on it to see what you have with a small load. A bulb can be hidden; painted. A resistor would work too,(larger the watt, the cooler it stays) I just figure a bulb is likely on hand already.
Tried the bulb idea, and it brought the output down to 18.2 vs 18.7. Would still like to bring it down a little more.....perhaps around 17 volts. (The Atlas coils have had so many problems I am afraid to "zap" them too hard". What value resistor would accomplish this? Thanks again!
