ABSTRACT:
A display panel is mounted to display a world map composed of a plurality of divided local zones. A touch switch panel is opposed to the display panel and comprised of a pair of spaced substrate films deformable inwardly relative to each other, a plurality of segment electrode films formed on the inner surface of one of the substrate films and aligned corresponding to the respective displayed local zones, and a counter electrode film formed on the inner surface of the other end of the substrate films in opposed and normally spaced relation to the plurality of segment electrode films. The touch switch panel is operative when one of the segment electrode films is selectively deformed inwardly relative to the counter electrode film to make electrical contact therewith to effect the activation of the one segment electrode film for designating the one divided local zone corresponding to the activated segment electrode film. The local time of the designated local zone is calculated and displayed in a display device disposed adjacent to the display panel.
