    • A capacitive touch switch and control device is provided. The capacitive touch switch and control device in one embodiment includes one or more capacitive sensor elements, one or more resistors, a capacitor, a capacitance/frequency converter, and an antenna including a positive branch and a negative branch. The positive branch and the negative branch synchronously and correspondingly receive a pair of signals from the microprocessor, the pair of signals each undergoing a 180 degree phase shift relative to the other, for shielding the noise acted on the capacitive sensor elements. When any of the capacitive sensor elements is touched, the capacitance/frequency converter outputs a frequency signal to the microprocessor, the microprocessor outputs a control signal that corresponds to the frequency signal to an electronic device to trigger corresponding operations of the electronic device.
    • 提供电容式触摸开关和控制装置。 一个实施例中的电容式触摸开关和控制装置包括一个或多个电容传感器元件,一个或多个电阻器,电容器,电容/频率转换器和包括正分支和负分支的天线。 正分支和负分支同步并相应地从微处理器接收一对信号,该对信号各自相对于另一个经历180度相移,用于屏蔽作用在电容传感器元件上的噪声。 当电容式传感器元件被触摸时,电容/频率转换器向微处理器输出频率信号,微处理器将对应于频率信号的控制信号输出到电子设备以触发电子设备的相应操作。
