[QUOTE="RadioGnome1971, post: 745415, member: 43595"] Sorry to revive this post from the death, but it is still the only sensible thing popping up when searching the interweb on this problem. I can add some findings to my reply back in 2017. Today I got fed-up with the problem again, and eventually noticed something. When putting some pressure on the on-off ring, while turning it to the off-position, suddenly made the behavior 'like it was 1999' again. Of course moving it by the nob with my index-finger the normal way, puts a fractional lifting-force on the opposite side of the ring. There must be something there, underneath, having to contact something. I applied the tiniest amount of contact cleaner around the ring, hoping capillary forces would drag it in. This improved things a lot! Probably there is a sort of hard-coded shut-down procedure in the contact-pattern on the business-end of the on-of switch. And these contacts got dirty and/or the whole assembly got a bit worn down. I did believe in the 'capacitive cause' of the problem, but now am quite convinced it is electric-mechanical.
