Coordinate Button can serve by the substitute of mouse for a computer or notebook. Between two plates piezo-ceramic structure is placed. The lower plate is hard and overhead plate is elastic. At pressure on an overhead plate piezoelectric effect appears (fig.1). A charges appear on opposite overhead and lower plates. A charges through a conductors transmitted in the coordinate of place.
