2 Position Dome Springs 1

[ssarcia]

I am trying to find some info on 2 position dome springs (ie: an inverting metal dome). I want to figure out some governing equations regarding stiffness and more importantly inversion point. I know tactile membrane switches are probably the most prevalent such application but haven't provided me with enough info.

Commonly used in snap-action pressure switches.

Try googling for "snap action diaphragm"
