A liquid-state switching device utilizes movement of a column of liquid, resulting from a change in surface tension of the liquid caused by electrocapillary action, to operate various switch means. The electrocapillary effect is induced across a single interface sets of single of mercury and an electrolyte or electrolytes. Filter partitions are installed to maintain the liquids in a proper relationship throughout variations in position of the switching device. Means are provided to assist the return of the column of liquids to their normal positions including a bias voltage, a permanently installed resistance, and/or pressurized gas pockets.
