Capacitive touchpad with physical key function |
摘要 |
A capacitive touchpad with physical key function comprises a soft flexible first conductive layer; a second conductive layer; and a soft flexible insulator layer disposed between the first and the second conductive layers. The insulator layer has at least a through hole for the first conductive layer to connect to the second conductive layer while the touchpad is pressed and cause the voltages on the first or the second conductive layers to change and thus to trigger a predetermined key function.
