Touch-control key, touch-control panel and touch-control terminal

A touch-control key, a touch-control panel and a touch-control terminal. The touch-control key comprises a touch-sensing layer (210), a pressure-sensing layer (220) and a shielding layer (230); the pressure-sensing layer (220) is provided below the touch-sensing layer (210), and the shielding layer (230) is provided below the pressure-sensing layer (220); when a finger or a touch-control body presses the touch-control key, the gap between the pressure-sensing layer (220) and the shielding layer (230) becomes smaller, such that an electrical signal sensed by the pressure-sensing layer (220) changes, and the magnitude of the pressure of the pressing of the finger or touch-control body is determined according to a change condition of the electrical signal; the pressure touch control from the touch-control body is sensed by using the touch-control key to enable the touch-control terminal using the touch control-key to respond to the pressure touch-control operation, such that man-machine interaction based on a touch-control key extends from a "time" dimension of long-time pressing to a "force" dimension of heavy pressing, thus enriching the hierarchy of man-machine interaction and user experience.
