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.
