Abstract
A reed switch assembly of a magnetic latching relay includes a movable reed, an immovable reed, a movable contact and an immovable contact. The movable contact and the immovable contact are disposed at respective ends of the movable reed and the immovable reed. The end with the movable contact of the movable reed is bent twice to form a reverse U-shaped end. The end with the immovable contact of the immovable reed is bent twice to form a U-shaped end. The reverse U-shaped end of the movable reed and the U-shaped end of the immovable reed are interlaced. The present invention further comprises a tension spring. One end of the tension spring is fixed to the reverse U-shaped end of the movable reed, and another end of the tension spring is mounted to a base of the magnetic latching relay.
