On any given key I can apply some pressure, but the key will not press down. When I push a little harder, the key goes down to the bottom.
Virtually all keyboards do this, have a peak in resistance that then falls off, regardless if whether they are rubber dome, scissor switch, buckling spring. Most mechanical switches.
The only key mechanism I can name off the top of my head that doesn’t do this is Cherry MX Red keyswitches (“linear resistance”), which are uncommon and in my experience only used for certain gaming-oriented keyboards. So you are pretty much guaranteed this behavior regardless of the keyboard you get.
Oh, and the very early Macintosh membrane keyboards, back in the mid-1980s, didn’t either, and I’ve used those. But that probably isn’t going to be a factor here.
