QUESTION
I’m working on a mechanism that uses this “latch” type spring to clamp something down. Does anyone know of any reference material or literature that would explain some basic calculations or a design methodology for this type of spring form?
I’ve looked around a lot and haven’t been able to find anything. The goal would be to design a spring form that is displaced/deformed X amount and provides Y force when displaced/deformed.
See drawing below:

I’d call it an “over center” latch. The calculations would be pretty straight forward when you understand how it works (moment about pivot reverses polarity).
