Claim:
An apparatus comprising: an outer housing; a display disposed in the outer housing; a bracket flexibly coupled to an inner surface of the outer housing and the bracket configured to pivot about a pivot point, located on the bracket, while the outer housing remains stationary with respect to the display; a scroll disc rotatably mounted within the bracket, the scroll disc rotating on an axis that is substantially perpendicular to a plane defined by the display, the scroll disc operable to cause a graphic element being displayed by the display to move in a first direction by a first predefined amount when rotated clockwise and to cause the graphic element to move in a second direction by the first predefined amount when rotated counterclockwise; a dome switch operable to provide an input to the apparatus, the dome switch mounted on a circuit board that is located on a plane parallel to the display, the dome switch configured to be actuated by the bracket pivoting around the pivot point responsive to a force applied to the scroll disc and substantially parallel to the axis; and a spring flexibly coupling the bracket to the inner surface of the outer housing, the spring configured to pull the bracket away from the dome switch responsive to the force applied to the scroll disc being removed.
