ABSTRACT:
A computer keyboard has multiple rows of cantilevered keys which are flexibly attached to common mounting strips. The rows of cantilevered keys are arranged to partially overlap adjacent rows such that the keys in one row actuate switch contacts aligned beneath mounting strips in the adjacent row. An interface between the switch contact membrane and a printed circuit board, and employing a portion of the dome sheet as supporting legs for the keyboard, are also described.
