Abstract
A touch knob includes a knob shell having a three-dimensional contour with a curved joint surface; an ITO touch sensor disposed on the knob shell; an auxiliary conductive unit with extensibility, connected on the touch sensor to form an overlapping area covering the joint surface, and the auxiliary conductive unit in the overlapping area having a conductive pattern corresponding to the touch sensor; and a surface coating layer having a three-dimensional contour corresponding to the knob shell and attached on both the touch sensor and the auxiliary conductive unit. An opaque mask surface is provided on an inner side of the surface coating layer. The mask surface cloaks the overlapping area.
