A repositionable label for mounting upon or proximate to electrical or other types of interfaces may identify devices associated with such interfaces. A label may include a static cling or other type of substrate that carries identifying information. The identifying information may exist in textual, symbolic, iconic, tactile, chromatic, and/or other formats, and may correspond to common types of electrical devices and/or appliances controlled through electrical and/or other types of interfaces. Such interfaces may include switch covers and/or switches associated therewith; fuse or circuit boxes and/or switches residing therein; outlets; power strips; and/or other interfaces typically found in households, offices, or other environments.
