ABSTRACT:
A long keybutton is stablized with a pair of arms and an interconnecting shaft. The ends of the arms are connected to the keybutton using a thin serpentine section which distributes stress and forces to improve life of the part, and permits integral molded keybuttons. The integral molded part with the stability of the portions of the keybutton permits the automated assembly of the stabilized keybutton with the keyboard frame.
