  • Electric hair cutting apparatus
    Patent number: 5259115
    Abstract: The invention is directed to an electric hair cutting apparatus in which a desired length of hair is adjustable by means of a preselector slide means (72). When the hair cutting apparatus is turned on, the drive motor (90) is operated only at the setting corresponding to the preset position. The preselector slide means (72) comprises a permanent magnet (100) having associated to it a reed contact (70) which is fixedly accommodated in the casing of the hair cutting apparatus. The use of the reed contact prevents beard hair from entering the interior of the hair cutting apparatus.
