…......................--- Turnout Control Box Parts List ---
=========================================
List of Parts Used:
I. 3 D Printed Turnout Switch Box or Control Panel (whichever you are using):
1-- 5 volt power supply.
1 -- 3D printed box and top or control panel to mount switches to the top of and components inside or under.
18 Inches or so – Wire from power supply to switch box or control panel ( I use 22 gauge ).
A few inches or so – Wire to wire components together ( I use 30 gauge ).
1 – DPDT toggle switch without center off.
1 – Momentary push-button switch.
1 – SPDT Slide switch.
1 – ¼ watt resistor – 220 ohms or greater ( higher the value the dimmer the light, I use 470 ).
1 – 500mm servo extension cable with the male ( big end is cut off).
2 – LED's of different color ( I use green to indicated the 'main' and red to indicate the divergent route ).
---------------------------------------------------------------------------------------------------------------------------------------------
II. Servo Controller mounted on 3D printed bracket or something else:
1 – Bracket to hold the servo tester ( you can make one or use the 3D one I designed )
1 – Servo Tester
1 – 10K Trim Potentiometer
A couple inches of wire – I use 30 gauge.
---------------------------------------------------------------------------------------------------------------------------------------------
III. Servo Extension Cable:
You can get Male/Female extension cable in various lengths. You might or might not need to add to the cable that is connect to the Turnout switch box that goes to the servo controller. You will need cable to go from the servo controller to the servo.

Picture of Parts used with some links that might or might not be current:
Above are most of the parts you will need and what I've paid for them. I've built over 40 hand-laid turnouts and if I get far enough with the layout will have over 100 turnouts so I bought larger quantities on most of the items above and that saved a lot. Most I got from USA suppliers on Ebay.
I picked up the 5 volt 10 amp power supply on Amazon but you can find it other places.

I also picked up the wire above on Amazon and really like it. I use it for the power supply and other projects. For the length between the power supply and switch box I twist about an 18 inch length and put heat shrink tubes near the ends to keep it from untwisting.

I use the 30 gauge above for the wiring inside the switch box and on the servo controller. Use the 22 gauge for other projects.

I found them for less than what is in this link but that seller is gone. Use the link to shop around and the price in the link is for two so not a lot more than what I paid.

=========================================
WARNING: One person bought Miuzei SG90 servos on Amazon and they didn't work.
Went 90 degrees each time they were powered on. I would stay away from them.
If you find servos that don't work let me know.
