Omron Mouse Button - Micro Switch (D2F-5L)

Pretty much the gold standard

Great repeatability, used for a filament sensor and replacing z endstop.

Great little switch

Very repeatable and accurate actuation. What more could you want from a switch? Oh yeah, it's got that clicky sound that we all love.

Good but Fragile

I got these for a Stealthburner, planning on using both an extruder and toolhead sensor. Make sure your printed parts aren't too tight, otherwise the force needed to install the limit switch will break it. I ended up breaking one, but the other still works fine.
