Oak Full-Travel Membrane (also written FTM on the label on the keyboard) is a progressive rate spring-over-membrane switch.
Variants
Cross mount
These have a typical cross mount on the slider's flat top.[1] A spring at the bottom of the slider applies pressure to the membrane, and this in addition to the return spring gives it its progressive rate feel.[2]
Flat-top
This appears to be the more common version. The slider is octagonal on top, and it does not appear to make direct contact with the membrane.[3] Full disassembly has yet to be confirmed and it is not clear how the switch works. Black and white sliders exist.[3]
