Abstract:
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.
