The SKQG performs excellently. Spec'd for 100 000 operations, but I tested them for 200 000 and they still did well with 30ms software debouncing. Unfortunately I forgot to measure the actual bounce times after the 200 000 switches at the time.
Be sure to place a small cap in parallel with the switch to keep the contacts clean.</p>

That's based on the comment below that sad this is the same button as on the Arduino Pro Mini</p>

Thanks</p>

In other words, if I use this switch to control whether or not two components are grounded, are the two components isolated when the switch isn't pressed?
Thanks!</p>

I can't figure out a way to match them other than by looking at the part footprint to make sure it's the same. Any better suggestions?</p>

Just a thought.</p>
