ABSTRACT:
A computer keyboard has a pointing stick integrally molded into and projecting from a surface of a plastic housing. Keyboard keys extend through holes in the same plastic housing. Strain-sensitive resistors are formed in a small location onto a circuit substrate. The same circuit substrate that carries the strain-sensitive resistors also carries conductive pads for the key switches. The strain-sensitive resistor location is bonded to the housing adjacent the pointing stick, but on an opposite surface of the housing from the pointing stick protrusion.
