RF 15 H short-travel keyswitch
RF short-travel keyswitches
General data
Application notes:
The RF 15 H key has an overall height of 12.5 mm and can be fully illuminated. When designing membrane keyboards,
we recommend using a key grid of at least 19.05 mm and a 0.13 mm overlay with area embossing over the keys.
You can use the O-ring (accessory) to block the key and use it as an indicator field or blank spaceholder.
