I thought he might understand it if put into different words. They are called a "make before break" switch, meaning all three contacts make before either of the others break.

Isn’t that what I said? They are the only pair in the upper switch stack that make and break

I don't have a manual in front of me, they are in another building, and unfortunately I don't have the contacts memorized (I should by now). All I can say is that TWO contacts must be closed to energize that coil. As the contact blade of one is pushed, all three contacts touch for a split second. When it reaches the full lift height, it opens one of them. If you follow the manual and adjust to the 64th of an inch, you will get it right. Be sure to start with the first adjustment and follow through to the last one, in the order they are written.

Hi, yes I have the manual, looking at the diagram it seems the popularity meter is triggered by contact IC, but this is one that stays triggered during play so I have doubts... Anyway, I just cleaned all the contacts from upper and lower set of contacts, it seems better but not solved: sometimes stills stays energized. Can you please tell me exactly which contact is the one to look into? Thanks

The upper switch stack has a set of contacts that make & break controlling the pulse for that circuitry. They have to be clean, grease / oil free and adjusted correctly. If you don’t have a manual I’m happy to email a copy of that page but I’m away until Monday

Dear all, today I switched on my hf100r after 3 months of stand by and I have 2 issues (previously it was perfect): I select the song, when then the disc is taken and starts to play the popularity meter solenoid gets activated but it stays activated, thus I have to immediately shut off in order to avoid the solenoid burning. I had a look at the popularity meter block and it seems fine, but for some reasons the solenoid continues to get current... Where does the signal come from? Where should I look? I also noticed a second symptom: pressing the reset switch on the back to stop playing the record does neither work anymore.
Any ideas?
