Topre switch's electronic switch mechanism is by capacitance. This means, there is no contact between electric conductors for the switch to turn on. The key does not need to hit bottom to activate.

Topre switch's feel came from its rubber dome, not the spring.

I don't like topre switch. It has a hit-bottom finger-shock problem. Topre switch, got this rubber dome, you have to hit with certain force, and because it is rubber dome, the dome collapses at some point and sucks you down, thus hit bottom and creates a finger impact shock feel. I don't have this problem with any Cherry MX switches, nor with IBM buckling spring switch, nor romer-g.
