Abstract: Tactile apparatus that, in electrical embodiments, comprises an electrically conductive dome; at least one outer edge portion of the electrically conductive dome that contacts a first electrical contact underlying the dome when the dome is in the electrically closed configuration; and an inner portion of the dome that contacts a second electrical contact underlying the dome when the dome is in the electrically closed configuration, wherein the dome is snap reconfigurable from the electrically open configuration to the electrically closed configuration, and wherein the dome includes a dome height enhancing protrusion at a top thereof. In particular embodiments, the at least one outer edge portion, the inner portion and the dome height enhancing protrusion are made of the same conductive material and/or the dome height enhancing protrusion is a non-interfacially integrated part of the dome.
