All good Ray!
Hate those self-rectifying faults...I think if I were in your shoes, then yes, I'd be having a really good look at the switch. Sounds like intermittent excessive voltage drop across it, as you said at one stage you had a spark at the centre lead but nothing out of the distributor (and I gather the rotor is fine) low primary voltage=low secondary voltage. Maybe loose/corroded terminal issue? Also might be worthwhile making a jumper lead with crocodile clip ends long enough to jump the coil 'SW' terminal straight to battery live and by-pass the switch and wiring if it happens again (esp if it happens again in an awkward situation)
