In some embodiments, a stylus for providing input to a capacitive touch screen, having a tip including or consisting of conductive felt, which provides a deformable conductive surface for contacting the touch screen. The tip is produced by felting base fibers (which are typically non-conductive) with conductive fibers. In other embodiments, a capacitive touch stylus having at least a first mode of operation and a second mode of operation, and including at least one conductive tip and switched circuitry (preferably, passive circuitry) including at least one switch biased in a default state indicative of the first mode of operation but switchable into a second state indicative of the second mode of operation in response to movement of the tip (typically, in response to exertion of not less than a threshold force on the tip). In some embodiments, a stylus having a conductive tip (e.g., a conductive, felted tip) and including switched circuitry (preferably, passive circuitry) having a first state which couples a capacitance to the tip, where the capacitance is sufficient to allow a capacitive touch screen device to recognize (as a touch) simple contact of the tip on the screen of the touch screen device, and a second state which decouples the capacitance from the tip, thereby preventing the touch screen device from recognizing (as a touch) simple contact of the tip on the screen.
