Classification: CPC G  H | IPC G  H

Claim 1:
2. The terminal control system according to claim 1, wherein the terminal key comprises:
a key shell, a capacitive sensing layer, a buffer layer and a substrate which are arranged in sequence, wherein
the key shell is configured to protect the capacitive sensing layer, the buffer layer and the substrate;
one end of the capacitive sensing layer is connected to system ground to forms a ground capacitor to the system ground, the capacitive sensing layer is configured to generate the inductive capacitance corresponding to the control instruction in response to a reception of the control instruction by the terminal key;
the buffer layer is configured to form an interelectrode gap between the capacitive sensing layer and the substrate; and form a deformation in response to a reception of the control instruction by the capacitive sensing layer, to generate interelectrode gap variation corresponding to the deformation; and
the substrate is configured to form an interelectrode capacitor with the capacitive sensing layer, and generate the interelectrode capacitance corresponding to the control instruction after the buffer layer forms the deformation.
