A Beginner's Guide to Force Curves
« on: Sun, 11 October 2020, 11:16:13 »
Hey all,

Being that it is now the 8 month birthday of the website, I'm super excited to finally get to share one of the documents I've wanted to write the most since I started on the website. Following up the essential reading that is my 'Beginner's Guide to Switches', I present the 'Beginner's Guide to Force Curves'! If you haven't read either of these then you definitely need to get on them to up your switch knowledge.

Beginner's Guide to Switches: https://www.theremingoat.com/blog/beginners-guide
Beginner's Guide to Force Curves: https://www.theremingoat.com/blog/a-beginners-guide-to-force-curves

Thanks for all of the love and support thus far along, and I would always love to hear back from all of you!

Cheers,
Goat

As an engineer, I would like to thank you from the bottom of my heart for such an insightful write up on force curves and how springs work. I think this might help take some of the Myth and mystery of how a switch behaves and why "premium" brand springs may not alter the tactile feel of a switch. Extra bonus points for introducing free body diagrams :)

One thing that might help people would be to start with a linear switch and then add the added complexity of a tactile bump. That way, they would get a nice graphical representation of hooke's law before we need to tell them that real life is actually more complicated then that.

After reading this, I really wish aftermarket springs were sold either by rate or with a specified deflection at their "wieight".

Thank you again for a nice insightful writeup.
