RACON short-travel keyswitches
RACON 12 i
General data
Application note
Low-profile keyboards with RACON 12 i components should be designed with a grid spacing of 15.24 mm. With this grid,
frame webs remain free between the individual keys. The overlay can be glued onto these frame webs; we recommend
area embossing over the keys for the overlays. If our RK 90 system design is used, we recommend the 9 x 9 mm keycaps.
