Unusual but nice
If you're bored by the usual tactiles, but still don't want a linear, this might be worth the experiment. The bump is all the way near the beginning, and it's almost imposible to not bottom out. If you care about the noise, this might not be the switch for you. If you care about the sound, it might be just the thing you'll like.
Switchs are lubed, and housings are very tight - no play in them at all. One in maybe 20-30 switches has a slight high pitched buzz, and not all switches produce the same frequency clack, but if you sort them out and bin them, you can get a VERY nicely sounding keyboard.
At the risk of having a lot of people frown at me - i really want to try these out with o-rings as well. Since the bump is at the top, there should be no noticable mushyness, but it might result in an even nicer thock.
