I really like how these switches look and work and I like that they have a connector for it. use if that's what you're into), and I always remove the normally closed wire. I connect them to the Arduino and the quick switching action is like a tactile switch but the switching noise is big. I got rid of the bouncing by "activating" on the initial edge and then ignoring the switch for the next 50ms. not bad, but be sure to plan for that in your software or you'll end up with a wrong switch.
