<p>A keyboard with a mode-switching function is provided. The keyboard includes at least one key, a pressure sensing circuit, an illumination module, a mode-switching program and a controlling unit. The mode-switching program is executable to enable both the pressure sensing circuit and the illumination module, so that the keyboard is operated in a pressure sensitive and luminous mode. The pressure sensing circuit is used for detecting the pressure, and generating a corresponding pressure-strength sensing voltage in response to the pressure. According to the pressure-strength sensing voltage, the illumination module is controlled by the controlling unit to emit either a first light beam or a second light beam.</p> |
