I’ve thought about this a few ways. I would love any feedback if I write something incorrect.
Use a pair of optocouplers. The tip and ring could control two LEDs independently while sharing a common ground on the cathode side. Then the collector and emitter hooks up to where each spst is. But would I introduce resistance from the phototransistor side?
I also know you can use a transistor as a switch, but not sure how to implement that correctly either.
Or am I just trying to be a fancy pants
and this would be easier as two ts jacks?
