This video shows IBM's molecular switch in action. The naphthalocyanine molecule contains two hydrogen atoms (shown in white) at its center. When a voltage pulse is applied using a scanning tunneling microscope (shown as a red field), these hydrogen atoms change position, jumping to different sides of the molecule. The change in position of these atoms alters the electrical properties of the molecule as a whole. This allows it to be treated as a switch, with the two positions corresponding to "on" and "off" states.
