RF
4 - 66 PCB Keyswitches
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
remain free between the individual keys.
The overlay can be glued onto these frame webs; we recommend area embossing over the keys for the overlay.
