An electrostatically controlled electrical relay switch is disclosed which includes two chambers joined together by a constricted region therebetween. A conducting liquid, such as mercury, is positioned in one of the chambers and the movement thereof between the chambers is controlled by an electrostatic field. Electrical conductors extend into at least one of the two chambers so that when the conductive liquid is moved into a chamber, the electrical conductors therein are electrically coupled to one another. In an alternative embodiment, the movement of the conductive liquid between the two chambers acts as a means for switching fluid or a light beam. A dielectric fluid could be substituted for conductive fluid in the optical or fluidic switch. Also more than two chambers are possible. In the case of multiple chambers they may be grouped in a string each closest pair being separated by a constricted region or the chambers may be grouped around a single constricted region. A combination of the two groupings may communicate in one switch.
