FIELD: electric engineering. SUBSTANCE: keyboard has two conducting layers which are spaced with possibility of contact when pressed and are connected to electric circuit from current leads. One layer is connected to front panel. Material with variable piezoelectric resistance is placed between layers. One layer is made of two metal coats applied to dielectric. Another layer is made as one metal coat applied to inside of front panel. EFFECT: increased functional capabilities. 1 dwg
