Is that spring the reason why the buttons on my 3456A have such a sharp tactile action when I press them? Is that abnormal and can that be alleviated? The seem overly noisy and hard to press.
Thanks,

Subject: [hp_agilent_equipment] Spring loaded Old Style Front Panel Buttons
I got a 9915 computer which uses the same leaf-spring loaded front panel
buttons as many older HP instruments (/e.g. the 3456A DVMs).
Three of the springs have fallen out and I need to fix that.
Are there any sources for these parts or ways to obtain similar springs or
even complete switches?
Any well known repair procedures that I should know?
I could possibly obtain some flat sheet spring steel and grind a spring to
shape using Dremel tools etc. but that sounds like a difficult and very
time consuming task. Also the length of these springs must probably quite
accurate.
Otherwise I would have to try something with external helical springs, glue
and other ugly constructions...
Thanks,
Martin
