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 re- main free between the individual keys. The overlay can be glued onto these frame webs we recommend area embossing over the keys for the overlays.
