[Diabolical Artificer]

"I realy do want a new word adding to the English language: "Pessimised"" That's a good word, I'll file that away in my lexicon of cromulent words.

"It is also poor practice to runs mains wiring up to a control panel area with signal control switches on it" Valuable advise, didn't know there was a construction section. I'm left with a bit of a dilemma, IE change the current arrangement and possibly reduce the amps re-sale value and also possibly leave myself open to litigation should something go pearshaped; if I do change it where to put said mains SW as room is tight. This is a two pipe problem.

" No doubt it was for reasons of cost, as things often are." If this was the case then why did manufacturers build radio chassis's out of thicker gauge steel than needed, use complicated tuning dial arrangements and sometimes over engineer old sets? I think part of the use of combined pot and Sw was just lazy design and thinking and cos everyone else did it. Humans act like sheep sometimes.
