A switching device has a cover including: a hollow content area housing a plurality of connectors; one or more openings designed to allow passage of one or more conductors; and one or more reflective agents mounted on the cover such that changing a physical location of an entirety of the cover with respect to an enclosure of an electronic device changes a location of the one or more reflective agents. A sensor is configured to sense the one or more reflective agents and output an electrical signal depending on the location of the sensed one or more reflective agents mounted on the cover. The sensor is positioned outside of the hollow content area of the cover. A controller is configured to change a state of the electronic device according to the output electrical signal of the sensor. The cover is mounted on an exterior surface of the enclosure.
