Nothing wrong with PCBs, as long as they're built properly!
Like the one inside my excellent EMU Black Morgan Plus 4 'Plug N Play' ECU built by ECU Master in Poland.
Sadly, whoever built the dash switch module for Morgan made some serious mistakes in its design and construction, it also seems likely some of the components chosen to go on the board were under specified, I very much doubt the Morgan PCBs were built in a modern facility like this.
What I’m saying is, much like TVR did with the later dash designs found from the Tuscan model on, Morgan went beyond their capabilities, they would have been far better off accepting their limitations and keeping the switching old school.
