Re: Cretinous idea - The combined volume pot and mains SW.
OK proof of concept. All from the odds and sods bin.
Old pot front mount as guide bush,
6mm aluminium rod from B&Q but a knitting needle will do just as well.
Standard on/off switch
Bracket from aluminium angle
Heatshrink tubing as coupler, the type that is lined by hot melt glue. This has just enough give to allow for slight mis-alignment but no rotational give if you have the rod and switch butted close together.
