|Take the panel apart and then take the switch apart!|
I have fixed this a couple of times by taking the light switch apart and using switch cleaner on it but the problem keeps coming back.
So, thanks to a Christmas present of Rimmer Brothers vouchers I bought a new switch entirely and fitted it today. Mind you it is a bit fiddly to do and the new switch needed to be taken apart before it would fit the hole in the panel. Then it's just a case of putting it all back together to find that yes all the lights work as they should - at least for now.
