I assume that the pressure switch is the round, black affair cabled in at the left hand side?
Reminds me of the PCB on the pressure switch of our works compressor, it failed so my boss ordered a replacement. When it arrived it looked exactly like the old one so I fitted it but when I put the power on the magic smoke escaped. Checking the part numbers it was a 24 VDC version and I'd just put 240 VAC into it
I might try a phone call tomorrow.Contact Stuart direct, phone or E mail, they have many spares.
I know just got a bucket full.
