Cylewet Vertical Switch Arduino: The Ultimate Solution for Seamless Vertical Switching - CYT1016 Review

Not suitable for breadboards. The design of the switch is very thin. If you need a temporary/small application, this works well enough.

I installed them by bending the tabs back to front and soldering directly to copper plate or Altoids tin boxes. I melted one in the process, but with a little care there were no problems at all.

Seriously, who the heck uses inches in their EDA software? You'll have to measure yourself if you plan on using them for anything serious, but other than that they work well.
