I need 2∗10 positions, and can only get 2∗6 or 1∗12.
For selecting cell count on a battery charger (no current at all).
Almost all handheld meters i've ever seen use rotary switches, and all i
took
apart had "custom" printed contacts. Oh, yes, there was one rotten piece
of bad engineering
that had four buttons instead. The damn thing had dozens of design flaws,
like blowing up
each time you pulled the current plug....

I could try to pull some mechanical stunt and stack 2 1∗12 switches.
I don't know if that would be possibe with the switches i can get.
But then, one switch for 2.50eur is not exactly cheap, not speaking of 2...
