3 Way Pad
I believe somebody already amde this but i couldn’t find it. Can be hady if you want to make possible to change “direction” of 3 different lines.
I hope it will be obvious from the images what it does.
- have input button which i connect to another side of a PCB (just passing a line)
- Redirect the input button to a MCU
- Use output terminal as input and redirect the signal to a MCU
