Remove the 2 turnouts on the right and you're left with just 2 turnouts. That is teh configuration I'm trying to wire.

Your diagram shows exactly what I'm trying to do.  Either the straight through mainlines are alligned or the 2 turnout diverging routes are.

Not exactly what you're asking for re: the LEDs, but maybe a simpler option to consider. I use a bi-color LED (red/green, use the 2-lead type, not the 3-lead type) at the control panel for my crossover (and all my turnouts, for that matter).

I'll refer to Kevin's diagram above, which correctly shows how to wire 2 Tortises to 1 DPDT switch. Connect the green wire from the Tortises just before it reaches the DPDT to one lead on the LED, then the other lead of the LED to the DPDT, shown in Kevin's diagram on the lower right. You want to have the bi-color LED green when the crossover turnouts are both straight thru, and red when the turnouts send the train thru the crossover. If you get the opposite result, just swap the LED lead connections. You have a 50-50 chance of getting it right the first time! I found it helpful to connect the LED in with test leads before soldering.

As Greg mentions, and per Circuitron's own literature, resistors are not necessary, the resistance of the stall motor is plenty.

Thanks Kevin, 

LEDs (3)

 with the turnouts aligned to the diverging route the LED on the control panel will be green and the LEDs on the mainlines (Straight routes) will be red indicating the turnouts will rout the train through the crossover from one mainline to the other.

with the turnouts aligned to rout the train straight through the mainlines will each have a green panel LED and the diverging route will be RED.

im trying to avoid having one led for each turnout (2) on the diverging route.

does that help?

I want three led's one one on the main and another on the other main and one in the middle showing that the crossover is active.

presuambly these are LED with resistors

wire them across the leads going to the tortois machines.   With the DPDT switch in one postion one of the leads will be +12V.  wire the LEDs you want to be ON with the anode (+ side) of the LED connected to that lead. 

wire the LEDs that you want to be on in the other switch position with the anode of LEDs connected to the other lead.

normally, LEDs without resistors can be wired in series with the switch motors because they draw ~10ma.   But it sounds like you have LEDs with resistors.  I'm also not sure if you can do that with two tortoise machines in parallel unless you only wire the LED in series with a single tortoise machine

I made a double crossover using Atlas turnouts but linkage driven by a single Tortoise.

You can use the Tortoise switch to operate the LEDs.



You can also use two wire bi-color (Red Green) LEDs in series with the Tortoise motor.

This will do two Tortoises from one DPDT toggle. Use pins 1 & 8 of each Tortoise.

I do not undeerstand your description of the LEDs.

Need wiring diagram for two turnouts with LED’s controlled by 1 DPDT toggle
Posted by gdelmoro on Wednesday, June 3, 2020 10:46 AM

Maybe some of you electronically gifted people can help an electronically challenged model railroader?

I have two paralell tracks with two Atlas isufrog turnouts creating a crossover between the two tracks.

I want to control these with 1 DPDT Toggle and two Tortoise switch motors. I would like to switch the toggle one way and have both switcches throw simultaneously so that in one position trains on the mainline will continue on their respetive  course and when switched the othe way the crossover is active and trains are routed to the other mainline. 

I want three led's one one on the main and another on the other main and one in the middle showing that the crossover is active.

The tortoises are powered from a 12v Power Supply, LED's are 12v

Can anyone provide a wiring diagram?

Gary
