Techniques for a circuit board for an input device are described. In at least some embodiments, an input device is integrated into a circuit board of an apparatus. For instance, a touch interaction region of the 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, an input device includes a switch such that movement of the touch interaction region actuates the switch to generate a click input event.
