Basic, convenient pushbutton. I got a couple dozen (roughly) of this style of button in a few different colors. 2 of them were DOA, one is flaky after a couple of weeks. For the price - not a big deal. Just test them first!

I bought recently bought 45 of these (15 Green, 27 Black, 4 White) for a project. Based on prior reviews, I bought a few extra but all of them worked. I will agree the push button action varies between the buttons from smooth to slight resistance. In addition, the button actuation varies a bit with most triggering with pushing most the way in and some must be completely pressed to trigger.

Overall, very good value. I would clearly by again at this point. I will post additional review if they start to fail in the future

I purchased a few of these buttons for a project. Unless you press and wiggle the plunger they make very poor contact. I figured it might be just one bad apple, but the whole batch was the same. If you don't care that you have to wiggle the button to make a connection, these are certainly very inexpensive. But if you want good solid connections each and every press, you need to look elsewhere. I found a replacement on Digikey that had the same hole diameter that just works. Of course they were $6 each.
