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.

Abstract: Particular embodiments of the inventive technology may relate to an electrical switch apparatus, and related methods, that include a conductive contiguity, alone with which two sequential electrical contacts may be induced upon application of force by a user, thereby effecting two or more distinct electrical events. Embodiments of the inventive technology may more specifically include a conductive contiguity having a truncated leg that enables inducement of a first electrical contact before a second, subsequential contact is induced.
