Hi all,
I made this AB switch, but would like to replace the 2 normal leds for a 3pdt Bi color led ring. Don’t want to use a battery, so I left that out. I replaced the resistance with a 470R. So far the ring lights up, but only one color. I would like the led always on and for example; A is red, B is blue. Since the 3pdt led is +/-/-, I figured I have to reverse power? But don’t know how to do that, and second; do I have to built in protection, such as a MOSFET or Diode? I have a reverse polarity cable to connect to my pedalboard powersupply, does that work? Thanks in advance, Marije
Fixt it, for who is interested;
