I have removed the switch assembly from the tuner and have a question. If I'm
not mistaken, the original switch had 10 fingers, each one contacting 2
contacts at any of the 5 positions. Is that correct? Based on what I can
surmise, that's likely correct but thought I'd check first.
Thanks,

I have an MN-2000 that somewhere in its long history, suffered a somewhat
catastrophic event that vaporized one set of the rotating fingers on the band
switch, damaged two of the contact points on the steatite wafer, and cracked
the wafer.
I found this switch which has potential:
The contacts are much like the one in the tuner; however, the rotating part is
different. The band switch in the MN-2000 isn't a traditional rotary switch in
that it doesn't make use of a wiper and, instead, the rotating fingers are like
a rotary shorting bar (for lack of a better way to describe it). Presumably if
you've ever looked at one of these, you know what I'm talking about.
Does anyone have any pointers on how I might go about replacing/repairing this?
The tuner is is in otherwise exceptionally great condition so I'd like to
repair it and use it.
