    Permanent Magnet Drive
    When a reed switch is driven by a perma-
    nent magnet, the selection of the perma-
    nent magnet and the determination of its
    distance relative to the reed switch are
    done according to the following steps.
    4-1 Permanent magnet drive method
    The following four patterns 1) through 4)
    illustrate typical methods to drive the reed
    switch by a permanent magnet.
