RF short-travel keyswitches
RF 15 short-travel keyswitch
General data
Low-profile keyboards with RF 15 components should be designed with a 19.05 mm grid. 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.
