Replacement switches for Rana Labs' C-Pad mod daughterboard. The Panasonic EVQP0E07K switches are rated by the manufacturer to have 0.74 N = 73 gf of click resistance, but in my measurements (with a manual tension gauge) they have generally been within the range of 47 to 65 gf, so quite a bit shy of the specified value, with quite some production variation.
These are rated for a lifespan of 5 million cycles, which in general is plenty (same as for Noble stick potentiometers), but for heavy C-stick users might need replacement after 2-3 years of usage, and in rare cases even earlier.
