Claims

[Claims for Utility Model Registration] (1) One end of an L-shaped yoke is connected to one end of an iron core around which a coil is wound, the other end faces the other end of the iron core, and one end of an armature is connected to the other end of the yoke. In an electromagnetic relay in which the armature is magnetically connected to the other end of the iron core so as to be swingable, and the armature is able to connect and disconnect from the other end of the iron core, and the movable contact opens and closes with the fixed contact by this contact and disconnection, the armature is connected to the contact spring. This contact spring biases the armature away from the other end of the iron core by its own force, and also prevents one end of the armature from strongly pressing the other end of the yoke. An electromagnetic relay characterized by being fixed to a terminal fitting. (2) The contact spring is provided with a U-shaped notch from the middle thereof to the terminal fitting side, and this notch is formed so that the U-shaped opening is located on the terminal fitting side, and the notch in the contact spring is the inner portion is located over a recess provided in one end of the armature;
The electromagnetic relay according to claim 1, wherein the electromagnetic relay enters into the recess and presses the armature when not energized.
