Claims

[Scope of utility model registration request]

An iron core wrapped with a coil, an armature that is swingably attached with both ends facing the magnetic poles of the iron core, and a magnetic path is formed between the iron core and the armature, and when the coil is energized, the iron core In a latching relay that includes a permanent magnet that holds the armature attracted to a magnetic pole and a contact spring that is pressed by rotation of the armature in one direction to close the contact, the position of the permanent magnet is determined by the position of the permanent magnet. and a latching relay in which one or both of the positions of the swinging fulcrums of the armature are shifted in a direction that increases the adhesion force of the armature to the magnetic pole of the iron core when the contact is closed.
