Maybe just a little WD40 down the shaft will do the trick - not a
whole flood of it mind you.

Don't want that precious console to wind up looking like Venice.....

WD-40 (fish oil as main ingredient or used to be) dries out.

Spraying the contacts for suspected electrical issues, only
temporarily fixes, and normally makes it worse afterwards.

Which is why I won't be doing that.

Indeed.

Instead I have contacted the sales director of Shuttlesound to find out why his
company does not keep adequate spares stock and contacted Bosch/Telex directly
to try and identify the switch.

Incidentally, despite the wording on the back, it was NOT designed in the UK at
all, but entirely by Dynacord. Probably explains the diabolical inter-channel
crosstalk.
