Techniques for a touch input device in a circuit board are described. In at least some embodiments, a touch input device is integrated into a circuit board of an apparatus. For instance, a touch interaction region of the touch input device is formed by cutting and/or etching a portion of the circuit board such that the touch interaction region is moveable with respect to adjacent portions of the circuit board. According to one or more embodiments, a touch input device includes a switch such that movement of the touch interaction region actuates the switch to generate a click input event.
