Craig and Henry,
Thank you for your recommendations and information. With the links
offered, I'll do some further researching and again, I thank you for the
solid lead and ancillary info.
Regards,
Fred

Hi Henry
Yes that is true although the preload on those is high and mass very low
so acceleration would need to be very high indeed to lift them (test to be
conducted I guess)
I have made a non-conductive pull pin for this purpose for the issue as
you have raised.
Currently used as part of a 'smart power switch/isolator'

Any chance you could use something like this?

Spring-loaded contacts like that can bounce under vibration, I believe,
although it might take rather a lot.
A potentially more significant problem with using phone/audio jacks is
that there can be brief shorts between adjacent *sets* of contacts as the
plug is inserted or withdrawn (unless the plug is purely a pull pin and
is
entirely non-conductive, e.g. plastic). Be sure your circuit can handle
that without loud surprises!
