  • Patent number: 5376765
    Abstract: A leveler suitable for use in multi-unit keys for a keyboard, such as a notebook keyboard, includes a J-shaped cantilever member interposed between a keycap and a base used to house the keycap. The leveler is rotatably attached to the keycap and rotatably and slidably engaged with the base. Upon actuation of the key, the slidable and rotatable portion permits the key to be compressed, while the rotatable portion attached to the keycap provides, through the action of the cantilever, a downward force upon the lower surface of the keycap. The distribution of this force via the cantilever mechanism provides a key leveling function, such that the keycap does not have a tendency to bind or stick within the guide portion of the base.
