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. Each cantilevered key has an elongated member extending between a common mounting strip and a key cap, whereby the elongated members are wider at the point of attachment to the common mounting strips than at a point adjacent to the key cap.
