Abstract
A touch knob which can transmit user touches above to a touch-sensitive surface below includes a base, a rotating shaft, and a rotating cap. The rotating cap defines a receiving groove facing the base, and the rotating shaft extends into the receiving groove and is connected to the rotating cap. The rotating cap is configured to rotate to transmit user touches in a bounded circular area, at least one conductive touch head is located on the rotating cap and in the receiving groove, and moves as the rotating cap moves. The disclosure avoids the need to cut or form any opening in the cover of the touch-sensitive surface or panel for buttons to be installed. A device using the above touch knob is also provided.
