ABSTRACT:
Disclosed is a slider type portable mobile communications device includes a top panel and a bottom panel. The bottom panel further includes one or more tapered keys that are tapered from front to back and associated recessed areas. The top and bottom panel are slidably movable in at least one direction with respect to one another such that they can define a closed position and an open position. When the top panel is moved from the open position to the closed position, it will exert a downward force on the tapered keys as it encounters them. The downward force is sufficient to compress and hold the tapered keys in their respective recessed areas within the bottom panel in the closed position thereby maintaining a consistent depth form factor for the slider type portable mobile communications device.
