[simpits-tech] controling a 28v circuit with a 5v

[Justin Messenger]

David, 
  that does sound good. If relays work fine then I'd be more than happy with that solution. The ones I found on Ebay at the moment however look like 1A. If you notice any at 20mA let me know. I only need 5 of them. 
   
  That looks like a slick little landing gear project that you made, exactly what I had in mind.
   
  Last night (way too late last night) I made a marker lights board with LEDs that is functioning and it looks nice to see it light up on approach. Next with the LEDs is a stall warning light. That should go nicely with my pedal stall shaker :)

  I used 5v low current relays to isolate and control the 28volt lamps.

I built this little circuit board to control the landing gear lamps 
for a friends sim.

It uses relays I purchased on ebay and is controlled by a Go-Flight 
Landing Gear module. I think I paid $5.00USD for 20 relays.
