Abstract
A telephone set comprised of a top part, a bottom part, a cover plate and a plurality of pushbutton keys. The keys fit into a plurality of oversize apertures in the top part and are held in place by the cover plate. A paper underlay is positioned over the cover plate to obscure apertures that do not contain keys. The oversize apertures in the top part allow the pushbutton keys to be removed without separating the top part from the bottom part.
