The main contact unit includes plural main contacts arranged in the axial direction of the tank. The resistance unit includes plural resistances arranged in the axial direction of the tank. The resistance contact unit cooperates with the resistance unit to form a resistant parallel circuit and it is arranged, crossing the axial direction of the tank. The main and resistance contact units are opened and closed by an operating mechanism arranged outside the tank.
