DEFINITION

Classification: 335/56

(under subclass 55) Subject matter wherein the armature structure comprises a globule, a metallic slug or other mass of material movable in a fluid and responsive to a magnetic field and freely movable within the magnetic field in such a manner as to complete or open an electric circuit between contacts and entirely free of any mechanical securing means. The fluid may be air, nonconductive liquid or the conductive

liquid itself.
