wolfman hal Ok Still a problem Rewired and double checked per all your advise. The switch throws the turnout correctly. The problem is that neither LED lights even when switch is thrown. The only difference between this switch on all the others on the layout approx 20 is that this is from a new pack that came from China. It reads RED Voltage 2.0-2.2 Green Voltage 3.0-3.4v Max current 20mA I am using 5mm bulbs. I have been using these on other projects with a resistor with no problem. This is the first time I am using this on my control panel. The control panel has NO RESISTORS as I am using Tortoise Switch Machines. I have No Resistor on any switch and they all work fine. Any Ideas guys Harold

Harold, I think you may have the wrong type of LED's. You're discription of the specifications indicates the color change from Red to Green requires a voltage amplitude change from about 2 volts to about 3 volts.
The Tortoise circuit does not change the amplitude of the voltage, it simply changes the polarity of the voltage. Buy standard red & green LED's that work on about 2 volts and use two per switch as shown on diagrams.
Or buy bi-color led's that work on about 2 volts. You may only need one of these bi-color led's per switch, because they are two led's in one bulb.
I think the ones you have, would need 3 volts to change colors.
