Hey Guys,

 

So I recently picked up a Atlas Remote Snap-Swith (HO) to expand simple oval (and knowledge) but am finding it difficult to find a straight answer on how to power this thing. My simple oval today runs great with my TIU/19vdc(5amp)/fixed 1 power supply, how should I power the switch? There are SO SO many forums on this topic, and people will go on about how Atlas switches suck or to use a "Capacitive Discharge" power supply, etc, but why is there no recommended instructions from Atlas?

 

I imagine the switch itself will need to powered by a separate vac power supply, recommended volts/amps?

 

And then the simple refuge siding off the switch, will it need another feeder from fixed 1?

 

Thanks so much guys.

I was able to find this switch wiring document performing a web search as well as a website with some instructions on wiring for DCC.

 

I am just assuming that you are using the TIU to operate a DCC HO railroad.

 

You'll need an AIU to control the turnouts remotely.

 

And yes, a separate transformer to supply power for the turnout would be prudent.

 

The siding power can be switched any way that you like. A simple SPST throw switch to the current hot supply and the other lead to the hot rail. You could use an AIU port to do the power switching remotely.

Thanks All. Looks like the Atlas answer for powering the switch is:

15-16 volt (AC) transformer that has a MINIMUM output of 2 to 3 amps

And correct I am talking about HO with a DCS signal from the TIU, not DCC, and no AIU in the mix, will be using the standard momentary switch supplied from Atlas to control the turnout.

 

So what about the siding?

 

Thanks everyone!

Nicholas,

Ok, so no AIU. The power connection for the siding should be just past the switch. The hot rail should be insulated from the switch hot rail and main loop.

 

The hot from the TIU should go to the toggle switch (SPST) and then from the switch to the siding rail.

 

Simple on\off power control for the siding. Then you won't have lighted cars lit or power to engine to prevent the odd ball launch.

 

You have some good answers for the switch control.
