Figure 1: A fantastic Kailh switch photo from Blitzenx51! There’s any number of different details people look into when they’re trying to pick out switches for their next keyboard build. However, arguably none of them are as vague and mysterious as the materials used to make housings and stems. Yes, even as manufacturers are iffy about their spring weights and newer brands are sketchy about who actually made their switches, differentiating POM from Nylon from Polycarbonate remains to this day the least understood parts of mechanical keyboard switches. For what it’s worth, I don’t have a fix for that either. As someone who has completed a master’s degree in chemical engineering focusing on polymer science, I understand full well that attempting to reverse engineer the formulas of even the most simple keyboard switch materials would take months on end and nearly free-range access to numerous analytical instruments that companies simply won’t hand over to you. However, that...

As we publish more articles in the "Mech Keys How-To" series currently ongoing, navigating the various topics and finding previous articles will only become more difficult. This thread will serve as a table of contents to help add some structure to the whole project. Feel free to also suggest future topics in this thread, as it will surely be easier to identify gaps and opportunities for further exploration when viewing everything as a whole.
