Abstract

A variable resistor is characterized in that the variable resistor is mainly composed of an insulating container, a first electrode, a second electrode, a conductor, a resistance liquid, a buoyancy body, a spring and a rotating shaft. The shape of the insulated container is circular; Central part of that insulate container is provided with a hole column. The hole column in the center of the insulating container is fixedly connected with the rotating shaft; at that cent of the conductor, a circular hole is arranged, and the conductor is slidably sleeve on the hole post at the center of the insulating container; a spring is arranged between the conductor and the insulating container. The conductor and the buoyant body together form a floating conductor. The spring forms the elastic mechanical connection between the insulated container and the floating conductor. A first electrode and a second electrode penetrate through the bottom of the insulating container and intervene in the chamberof the insulating container. A motor starter having a variable resistor as described above. The invention has the advantages of simple structure, long service life and low cost.
