I think my build is working the way it is supposed to, so I didn't post in troubleshooting.
I'm building a 2-channel loop switcher that is intended to be controlled by 2 switches connected via a TRS cable. I think I made several assumptions that were incorrect. My real question is: What would be a correct way to implement this?
I have two non-latching relay bypass modules in this. This is my first time using the non latching version. After working through a few issues, I removed the TRS jack and tested by tapping the footswitch leads together. One thing that surprised me was that after I tapped a pair together, that relay stayed on. I assumed that non-latching would behave like a momentary switch, and the relay would switch off as soon as the wires were no longer connected. A related assumption was that I should use a momentary relay module, so that my controller can own the "state" of the relay because it has the latch.
The next assumption I had was that I could connect the NE555 side of the FS to the TIP and RING, and the other side of the two to ground.
So now I have this 1590B crammed with 7 phone jacks, a dc jack and two relay modules. There's no room for a 2nd control jack if I need to separate them. But I could yank out the modules for a better solution.
