Abstract: A hybrid digital analog key switch is designed to generate both a digital signal and an analog signal (DA) from a single key switch after the key is depressed. A pair of spring metal electrodes are electrically coupled to up and down movement of the key stem, and a force sensor is configured on a bottom side of the key module. Both a digital signal and an analog signal are generated when the key is depressed by a user.
