If you pry open a typical switch, you’ll probably find that its internals are quite complex. Inside, there might be a small spring-loaded roller that travels over a tiny hump or an intricately shaped metal leaf that “pops” when pressed firmly enough. The purpose of these mechanisms is to keep the switch firmly in place until sufficient force is applied, at which point it snaps immediately into the new position. This nonlinear behavior provides satisfying tactile feedback, reduces sensitivity to vibration and other accidental inputs, and prevents the switch from resting in any state other than “fully off” or “fully on.” The flip side of this approach is that once the mechanism gives in, things happen quickly: The contacts are pulled apart or slammed together at a considerable speed. Because metal is elastic, this motion produces some vibration that manifests as electrical glitches lasting from tens of microseconds to a few milliseconds. The effect is known as switch bounce.

I know about switch bounce but I've never seen it explained so clearly. Usually electronics books will say "mechanical switches will bounce before settling" and will then describe a circuit or algorithm to deal with it. What's always missing is a plain English discussion of the why and how.

While I don’t expect one book to teach it all, I would like to see how it compares to the current crop of books and why is it better. The sample chapter left me very unimpressed and the book looks like it’s meant to be more for a coffee table and less for actual hands on usage. I don’t see a way that someone would put this into practice without an accompanying practice/lab book.

Speaking of covers, Open Circuits: Inner Beauty of Electronics has a much more honest yet intelligent cover to it. Each page is both informational and extremely well done. Someone who has no knowledge of electronics or electricity can walk away learning something because it shows how things physically work with photos. The visual itself is almost self explanatory as a still image of different materials and how they are arranged.

My actual picks, are the likes of Floyd or Melvino, the Charles Platt one that has loads of circuits to build, and of course the clumsy but informative Forrest Mims series of books. Then you can get into Elicia White’s Embedded or any other assortment of more advanced books on power electronics etc.

Open to be proven wrong but yeah. I would have expected more because I don’t know of any book on this subject other than Art of Electronics and maybe Microelectronics by Sedra (or Razavi) that gets this much praise. Yet it started getting this praise before it was even released.

I remain skeptical.
