This has been seen in some C5s and was attributed to water ingress into the switch panel causing contamination and sometimes corrosion of the contacts.
I had it one one of my C5s and James (Hell Razor5543) found that the cure was to remove the switch panel, dismantle it and clean all the contacts with contact spray (Servisol) or isopropanol.
Aslo using the rubber (eraser) on a pencil on the contacts helps.
