ABSTRACT:
A switching apparatus for an electron device, for controlling movement of an image on a display unit, including a plurality of pushbuttons being provided on upper surfaces with directional symbols which represent upward, downward, leftward, rightward directions and random or non-linear paths of travel in which the image displayed is allowed to move. When the pushbuttons are pressed, control signals are transmitted to a control circuit of the electronic device. The pushbuttons with the symbols indicating the four directions are arranged in a cross form, while the pushbuttons with the symbols indicating random and/or non-linear paths of travel are arranged between the pushbuttons forming the cross arms. Further, the pushbuttons with the directional symbols are arranged around a center pushbutton for stopping movement of the displayed image. The pushbuttons are made of a resilient material and assembled as a single unit.
