An object can depress an input device, such as, for example, a function button in an electronic device. A resistive element having a mechanically resistive force can be disposed to resist the depression or movement of the input device. One or more electrodes can be disposed to provide a measure of capacitance based on the depression of the input device. A shield can be disposed to reduce the parasitic capacitance between the one or more electrodes and the object. The electronic device can include a fingerprint sensor operably connected to at least one of the one or more electrodes.
