Very nice chassis and PCB by the way digi01!
You obviously designed it yourself.
Would you mine publishing the design?
Although Marcello´s PBC´s are so tiny.

Hello Jens,
the shorting relay's advantage is that this device avoids both the turn-on and the turn-off bumps, shorting quickly the outputs within few tenths of second.
