Topre Switch

Topre switch is a keyboard switch made by Topre Corporation, of Japan. Mostly famous due to its use in Happy Hacking Keyboard, from 1996 to about 2015.

Switch Mechanism

The electrical switch mechanism in Topre switch is 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 key feel came from its rubber dome, not the spring.

Topre Switch Review

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 Buckling Spring Key Switch , nor Romer-G Switch .
