Is it possible you were thinking you had to bottom out the keys on a mechanical keyboard? Good switches have a fairly long travel, but it's important to note they're not designed to be bottomed out, they're designed to be pushed to the activation point and then released. Where that activation point is may be harder to detect on some switches, but "clicky" switches like Cherry Blues have a strong tactile indicator.
I totally agree about bottoming out. It's more about the amount of force needed to trigger the switch, which on a capactive touch would be 0. I use o-rings too to decrease the length of the throw and to make bottoming out quieter and less impactful if it happens on accident. Mechanical keyboards just don't agree with my hands and wrists sadly.
