Abstract: A magnetic latching relay includes a casing containing a coil assembly, an electrically conductive plate and a static plate. A reed assembly is installed on surfaces opposite to the electrically conductive plate and the static plate and includes a reed, a pull-to-disconnect plate installed onto the reed, and a contact formed on the pull-to-disconnect plate. The casing includes a pushing latch latched to the coil assembly. If the relay is connected, the contacts of the reed assemblies of the electrically conductive plate and the static plate will touch each other, or else the pushing latch will be moved axially along the static plate and inserted between the pull-to-disconnect plates of the reed assemblies of the electrically conductive plate and the static plate to separate the contacts, so as to monitor the connected/disconnected status of the relay. An external display device is provided for displaying the connected/disconnected status.

Abstract: A relay contact system includes a first conductive plate, a first resilient plate, a second conductive plate and a second resilient plate. One end of the first conductive plate is a free end, and another opposing end is a connecting end. One end of the first resilient plate is a free end provided with a first contact, and another opposing end is a connecting end. The connecting ends of the first conductive plate and the first resilient plate are connected together. The free ends of the first conductive plate and the first resilient plate are arranged in the same direction and form a first zigzag configuration. The second conductive plate and the second resilient plate having a second contact on its free end and form a second zigzag configuration. The first and second zigzag configurations are connected or disconnected through the first and second contacts.

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.
