A solenoid is provided which, in the preferred embodiment, has a housing
having an axial opening in it. The housing has a divider mounted in the
axial opening to separate the axial opening into a first segment and a
second segment. Respective ones of a first pole piece and a second pole
piece are located on opposite sides of the divider. The first pole piece
is moveable with the first segment between an extended position and a
retracted position, the first pole piece having a plunger positioned at
an end of the first pole piece. A permanent magnet is moveably mounted
from the axial opening and is moveable independently of the second pole
piece between at least a first position adjacent to the divider, and a
second position adjacent the second pole piece. The construction provides
a fast acting, low cost latching solenoid construction.
