Abstract
A force-sensitive key module and a force-sensitive switch structure are provided. The force-sensitive switch structure includes a first protective layer, a second protective layer, a first conductive layer, a second conductive layer and a force-sensitive layer. The first protective layer receives a pressing force. The second conductive layer is aligned with the first conductive layer. The force-sensitive layer is installed on the first conductive layer or the second conductive layer. When the first protective layer receives the pressing force, an electric connection between the first conductive layer and the second conductive layer is established, and the force-sensitive layer generates an analog sensing signal in response to the pressing force. When a magnitude of the pressing force is changed, the analog sensing signal is correspondingly changed according to an impedance change of the force-sensitive layer.
