AFDS warning light circuiting

Hello,

I'm very new here and in cockpit building also. I have started my 737NG (booooring yeah) and have question about connection of afds pushbuttons with leds integrated to OC mastercard.

I have NKK switches with bicolor leds - red and green. They give wonderful yellow and red colors. But the problem is that this led has common anode. And OC mastercard - common gnd. I'm newbie in electrical circuiting also, but after reading many docs on the new I have decided to use transistors.

I would highly appreciate any comments on my circuit bellow. Switches are standing for master card outputs, one for red and one for green and are used just to actuate transistors with minimal current.

The circuit is below:

Use the circuit as it is. Instead of the switches use outputs of the OC mastercard to control the transisitors. That's all what you have to do to get it running (+ some piece of SIOC code :-)

Thanks Ruediger.

You have very nice website and 737 sim.

See U on IVAO :)

First circuit ever done by myself. And, wow, it works!

Probably, this one would be better..
