Editing Fujitsu Libertouch (section)

==Description==
Fujitsu Libertouch switches use [[buckling rubber sleeve]]s for tactility. The stock sleeves in the [[Fujitsu FKB8540]] are rated for a 44 cN tactile force, and the keyboard shipped with 15 additional sleeves each<ref name="Imgur" /> of 34 and 54 cN, for user customisation, along with a [[keycap puller]]; the details of the replacement domes are given in the press release.

The press release appears to indicate that one of the design goals was to provide pretravel, with [[force curve]]s showing the Libertouch actuation point occurring higher than it would in a normal rubber dome over membrane switch.
