How about this for a ZIF design:
The contacts take the form of tubes with slits cut axially all round leaving
rings uncut top and bottom to form a sort of tubular cage with no roof or floor.
If the top ring is twisted while the bottom one is held the tube will collapse
to a hyperboloid "cooling
I don't think ZIF sockets are necessary -- too much complexity -- but a LIF
(low insertion force) socket would be cool.
Imagine a socket consisting of a solid round cylinder core, with spring
tensioned contacts surrounding the core, that would press against the pins
when the tube is placed ove
I would definitely pay for ZIF IN-18 sockets :)

I still want to rotate the tubes, but I need to come up with a surrogate

A ZIF nixie socket! Now that
Yep, this exactly happened to me. A tube suddenly started having problems
lighting some digits. Then eventually it stopped working altogether.
I caused it because I was swapping the tubes too much. The repeated
removal/insertions caused the tube to leak at the pins.

Thanks Gene -- I'll keep an eye on it and let you know.

When you have a sudden performance issue, it's gas. Especially when large
sections of large-area cathodes go dim. Poisoning from sputtering affects small
sections and is observed over longer periods of time. I'll bet that tube will
start going pink soon.

Gene, please explain how you know this is the case.
Thanks

You're all wrong, it's leaking gas through the pins.

This is an issue that is most obvious on clocks with lots of
functionality. If there are different modes/menus that display numerals
on a tube that are not normally lit as part of the clock, then you'll
see this. Best advice is to take full advantage of automated
cathode-poisoning prevention

One of the IN-18s in my Nixichron has started to fail. I don't know if it's
cathode poisoning or some other failure mode.
In the 10's hours position, several of the digits are not lighting
completely, they are dark toward the bottom of the tube, probably the
bottom 1/3 of the numeral.
