Abstract
A magnetic latching relay includes three control windings disposed about an encapsulated reed switch having a pair of reeds constructed of a remanent magnetic material. A first winding is disposed about one reed and second and third windings are disposed about the other reed. The windings are arranged so that a current pulse applied to the first and second winding generates magnetic flux fields in the same direction that produce magnetic poles of opposite polarity at the contacting ends of the reeds and causes the contacting ends to close while a current pulse applied to the first and third windings generates magnetic flux fields in the opposite direction that in turn produces magnetic poles of like polarity at the contacting ends and causes the contacting ends to open.
