I would like to build a control panel for my conventional O gauge tinplate layout.  I have been searching for suggestions on how to build the panel and think I found what I need for construction materials.

I would like the panel to display whether  power blocks are turned on using an LED light or one color LED for power on and another color for power off.  I have been reading about bi-color LEDs but many of the threads are several years old.   I also need to include toggle switches on the panel to turn the power to the blocks on and off.  I also probably need some toggle switches for street lights and building lights.

I have 11 O-22 switches in my layout and would like to have green/red LEDs to indicate which leg of each switch is open.   Again, I am considering using red/green bi-color LEDs for each leg of each switch.  I am considering using 3mm for this and 5mm size for the power blocks.

I have several questions:

  1. Do you know of recent posts which would help me with this project?
  2. Should I use a different color pair for the switch blocks?
  3. Do you have any specific suggestions for sources for the LEDs and the toggle switches?  Resistor sizes for the LEDs?
  4. How best to wire these lights to indicate the direction of the O-22 switches? 
  5. Has someone come up with a better way of accomplishing the tasks for my control panel?
  6. Did I post this in the proper forum or would the O gauge forum have been better?

Any suggestions and input will be appreciated.

You could get non focused red and green LED's for the switch controllers,  They come either bayonet or screw base, I have them in mine and they look sharp.  There are some you tube videos for model railroad control panels, I will dig up a couple of links for you.  I would think you really don't need anything bigger than 3mm, those are pretty bright.  I can post a link for you for the resistors based on voltage used as a power feed to the control panel lights.  You can have switch positions on panel connected to the switch machines and they will light up according to the way they are thrown..LED's for the control panel are really cheap on Amazon, you can get like 50 for $10.00...

Marty, thanks for the reply.  I ordered some sample red and green LEDs as well as warm white and white (I think that what what they were called) from Town and Country Hobbies.  Do you have a better source I.E. less expensive bulbs since I have about 20 switches (although only 11 are being used now) and each switch uses 3 bulbs?

Any other links will be appreciated.
