[Boatanchors] Removing switch with knurled nut

[Al Klase]

Hi Ian,

I don't remember the specifics of the RAL, so these are general suggestions.

1 - Is there a hex nut behind the panel?  Loosen it with a thin wrench.

2 - Attempt to rotate the switch itself.  (This is no good if the hole 
is D-shaped, but give it a try.)

3 - Apply heat to nut with soldering iron.

4 - Protect the panel with thin tape; magic tape, vinyl electrical tape, 
etc., and have at the nut with vice grips.

Just some thoughts,
Al
