OUR PART # XK-A-557-R
These plungers fit into the deck between the keycaps and rubber membrane contact on most XK-series X-keys. This is a replacement part for lost or broken key plungers. Not compatible with X-keys Sticks.
Note: Replacing factory installed key blockers on an XK-60 with key plungers and caps will not add keys to the device as there are no functional electronics under the installed key blockers.
