Mitsumi KFK Type is a rubber dome over membrane switch and OEM custom keyboard type from Mitsumi.


KFK Type is a typical three-layer membrane arrangement with pressure domes. The rubber domes are discrete and sit within four short walls that help keep the dome in place. The illustrated (ideal) force curve is similar to that of Topre switches.
