RF short-travel keyswitches
RF 19 short-travel keyswitch
General data
Application notes:
RF 19 keys offer a large actuation area. When designing low-profile keyboards with a grid of >= 23 mm, 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 overlay.
