In accordance with an example embodiment of the present invention, an apparatus is disclosed. The apparatus includes a base element, a key top, a single dome switch, and a capacitive sensing system. The key top is configured to pivot in relation to the base element. The key top has a center area and a peripheral area. The single dome switch is between the base element and the key top. The single dome switch is configured to provide tactile feedback in response to a depression of the key top. The capacitive sensing system is configured to sense a capacitance corresponding to a distance between a portion of the peripheral area and the base element. |
