help! Need search term!
(OP)
Hi! I need a "spring" that behaves like a dome switch, but bigger:
the output of which would be a step function if plotted displacement vs. force. (there is no electrical requirement for this thing)
I hope for limited travel (<.050"), with a force threshold of about 8pounds. The item woudl need to have an outer diameter of about .875", and a bore of at least .50".
please comment on feasibility (this is a pie is the sky mechanism, I'm not sure it can be done, but would solve certain problems if so). Also, search terms for said item if I have described an off-the-shelf product! I will, of course, be calling my spring expert, but I like to approach manufacturers with a clue of what I really need...
thanks

RE: help! Need search term!
Does it has to snap through (Bi-stable)? If yes, how much force is needed to return it to previous position?
RE: help! Need search term!
Yes, I'd like it to snap through at about 8#, and return to original shape after the force is removed.
The concept being: a small handheld instrument, shaped like an electric toothbrush. Imagine attaching the "disposable toothbrush" to the body of the unit by pressing the two together. I want a tactile feedback that the person has installed if pressed together with enough force. I want the displacement to return when the force is removed. there's not very much space (axial, nor radial), so I'm looking for a space efficient solution.
other ideas are very welcome- I'm just spit-balling here.
