News Roccat debuts Titan mechanical keyboard switches

With all the custom (well, semi-custom) switches knocking around now, I'm surprised nobody has made a discrete buckling-spring switch (even if it's not able to fit into the common Cherry MX envelope for back-compat) that does not require a single-layout full capacitive/membrane sheet to operate as with the Model F/M and Unicomp. Topre has discrete capacitive domes and their patent has expired (e.g. clones exist like the Noppoo) so it should be technically feasible. AFAIK the closest was an obscure Alps switch with a little arm that hits the spring to cause it to buckle.
