I have a DPDT centre off switch that controls a model railway turntable - see attached image - and I want to add 2 LEDs to indicate direction of travel of the turntable either clockwise or anti-clockwise. How do I do this? I believe blocking diode/s can be used. I hope you can help. Thank you
I have a 240vAC to 12v DC power pack which has a reading of 17.7 v DC output with no load. I intend to use it as a 12v DC supply to power signals on a model railway. The signals are red & green LEDs with suitable resistors. I know the output on the power packs are sometimes higher than specified on the pack label. Would this circuit be suitable for my purpose to control the output to 12v DC?Thanks
