ABSTRACT:
Keyboard switch assembly comprises first and second insulating supports having opposed spaced-apart first and second surfaces. The first support is a flexible film and has circuit conductors on the first surface thereof which extend to switch sites. Each switch site has a pair of spaced-apart switch electrodes. The second support is a rigid one piece molding having a bezel which surrounds a sunken surface. The first surface of the first support is disposed against the sunken surface. The sunken surface has recesses therein at the switch sites and the floors of the recesses are covered with conductive material such as conductive ink. The floors of the recesses are the second surface. A switch at a switch site is closed by pressing on the first support so that spaced-apart electrodes both contact the conductive material on the floor of the associated recess in the sunken surface of the second support.
