Abstract
A keyboard assembly for a multiple button array in which each push button is individually pivotal about a resilient hinge which is deformable throughout its length or a "living hinge" mounting to a support structure. The engagement of the hinge mounting to a push button is located adjacent the end of the button most remote from the connection of the hinge to its support structure. The hinge mechanism for each button comprises plastic straps extends along both sides of the button to the connection to the button. The hinge axis for the straps is spaced a distance from the near side of the button to produce a button movement of a translatory rather than pivotal movement. The button array disclosed is suitable for use as a telephone push button dialer.
