*** A rare size of hardware.  I found a ceramic switch wafer in my old 
"switches"
box - probably been in there for 50 years.  It's not the same as the 
ones in the CX7 - the ceramic is thicker.
But I bet the contacts are the same.  So just to practice...

I drilled out one of the contacts with a Dremel, using a pointy-tipped 
conical burr.  That was easy, it popped
right off.

Then I measured the diameter of the hole.  I found a piece of brass rod 
that was slightly larger, chucked in my Sherline lathe, and turned it 
down...just a bit.  OK, it slipped right in.  A good slip fit.  Caliper
says it's now .0930 inches in diameter.  Or 2.34mm.

I'm tempted to just turn this bit of rod into a brass rivet. No standard 
hardware will be as tight & precise
a fit.
