PURPOSE: An automatic control float switch for the control of a water level is provided to accurately control the angle of a ball bearing by directly combining a limit switch insertion cylinder unit with a ball bearing fixing groove in a lower float. CONSTITUTION: A lower float(100) is formed into a cone-shape. The upper combining projection of an upper float(200) is combined with the lower combining groove in the lower float. A limit switch is combined with bolt with a limit switch insertion cylinder unit. A ball bearing is arranged in the bearing fixing groove of the lower float. The ball bearing vertically moves along the water by enabling the upper float to be combined with the lower float. The limit switch is turned on and off by the vertical movement of the ball bearing.
