DEFINITION

Classification: 335/55

(under subclass 47) Subject matter wherein the device includes significant armature structure, not comprised of the liquid itself, and whereby at least one movable contact is caused to complete an electrical circuit through the medium of a conductive liquid. The liquid may comprise the fixed contacts or electrodes or may be retained in a reservoir from which the fixed contacts are wetted by capillary or other action.
