Abstract
An improved low liquid level float control apparatus particularly adapted for use in vessels or tanks containing a fluid of the type utilized in liquid vending machines is disclosed. An electronic control unit has a probe section extending downwardly therefrom containing a reed switch, which is activated by the passage of a first magnet located in the lower portion of a float vertically along the probe section. A second magnet is secured along the upper portion of the float. Metal stops are provided along the probe section to determine the range and movement of the float and to effect a time delay, thus reducing the possibility of intermittent on-off operation of associated pump elements.
