Solder is the right answer. The switch will withstand a moderate amount of heat, when applied to the post/wire, but don’t let it “just cook.” I recommend you also use heat shrink or silicon over the posts to keep moisture away from the wiring and posts. Corrosion is not a serious problem, but the limit switch is of high quality and should last a very long time if it’s protected just a bit.

I am at the point of wiring up the nose gear limit switch on my IV and was looking at options for those tiny posts.  Definitely too small for a crimp on.  A female molex is too big.   The female D-sub pins I have seem too small.     Did a search in the archives and did not find anything.   So what did folks do to connect to that itty bitty limit switch.  Did you simply solder it?  If so, did the heat damage the limit switch?
