Switch machine wiring help!
Posted by Musepro on Saturday, February 19, 2005 6:02 PM
Hello everyone!

I am currently building a 14x14 foot HO layout. For budget reasons, we've chosen to use Atlas code 83 #6 Super Switches, but also purchased 4 of the new #8 Custom Line turnouts for mainline crossovers. These crossovers, along with the #6 turnouts in the hidden staging, will be powered with the Atlas UTT switch machines. I'm not concerned with powering the frog on the #6s because their frogs are short and our loco wheel bases are long enough. However, the #8s have very long frogs that I reasoned needed to be powered. Therefore, I purchased 12 of the standard UTT machines for the staging tracks and 4 of the Delux UTT machines for the crossovers, so that I could use their built in relays to power the frogs. I am operating these machines using a diode grid with SPST push buttons.

My questions is: Is there a way to use red/green LED route indicator lights on the control panel without using Atlas relays? I know I can wire them off of the crossovers with their built in relays, but I also want them for the staging tracks, which do not have relays (due to a 100% increase in price of machine for the built in relays). Thanks for any help!

I got to thinking and I realized that I dont even care if there are route indication LEDs, just some way that I can have point inidcation on the panel. Is there a way to wire an ON-ON toggle switch to twin solenoid machines? A center off momentary toggle isn't any better than push buttons without LEDs. The Atlas turnout control boxes kind of offer point indication, but they're too big to mount on a panel. Perhaps there are SPDT momentary slide switches readily available? (though they're a bit big in size as well) Any help would be great! Thanks!

There are several ways to proceed.

One, use the Atlas relays to control LEDs orlight bulbs as panel indicators.

Two, use a SPDT toggle (NOT momentary) PLUS a NO pushbutton at each location on the panel

Three, Take a look at some of the circuits on Rob Paisley's web site such as this http://home.cogeco.ca/~rpaisley4/ToggleTwin.html and build one for each turnout. Uses regular toggles and/or LEDs on twin coil mahcines

Four, instead of Atlas switch machines, use Circuitron Tortoises. They can be controlled b a simple DPDT toggle, no momentary action is needed. The machines themselves have DPDT contacts that you can use for signalling, powering the frogs (probably a good idea on the #8's), etc. With a Tortoise you can add panel LEDs jus by putting them in series with the Tortoise motor - the internal resistance of the Tortoise motor is just right to limit current to LEDs, no extra resistors needed - just add the LEDs. Simple.
