Re: Fuchs ODS30 footswitch problem
I'd guess just get a separate means of providing 12v (or 5v depending on the relays) to the footswitch and ensure that it's working. The flickering means to me, though, that the contacts on the switches may need cleaning. Intermittent like that implies poor connection. Either that or internal wires are not providing solid connection and need reflow/repair. it's a pretty simple continuity test inside as well between connections to ensure you have good connections.

Cool, nice find! Knew it couldn't be too complex. I've fixed a few footswitches and they're generally pretty straight forward.
