Abstract
An input device includes a keycap, a first electrode disposed to move in response to movement of the keycap, a planar array of electrodes extending at least partially under the keycap, and a sensor. The planar array of electrodes includes a second electrode, a third electrode, and a fourth electrode extending between the second electrode and the third electrode. The sensor is coupled to at least one of the second electrode or the third electrode and configured to generate a signal indicative of a change in capacitive coupling between the second electrode and the third electrode. The change in the capacitive coupling may result from movement of the first electrode.
