組立性を向上することができる。In order to achieve the above object, a first aspect of the present invention is to apply a valley portion of a substantially L-shaped armature to a fulcrum provided on a yoke of an electromagnet, and direct the armature toward the fulcrum. And push it with a hinge spring so that one end of the armature faces the iron core of the electromagnet.
With the other end of the armature facing the switch mechanism, the armature is swung by the suction action of the iron core, and the armature facing the iron core is suppressed from the middle in an electromagnetic relay that pushes the switch mechanism with this armature. The electromagnetic shock relay spring, which acts to reduce the impact on the iron core, is extended from the hinge spring to form an electromagnetic relay. Extend the shock absorbing spring from the hinge spring,
The impact on the iron core was reduced by suppressing the movement of the armature toward the iron core. Since the hinge spring and the shock absorbing spring are integrated, the number of parts can be reduced and the assemblability can be improved.

When a spring load characteristic line is drawn on a graph with the spring load as the vertical axis, the spring load characteristic line to which the shock absorbing spring is added is within the range of the suction force characteristic curve before the shock absorbing spring is extended from the hinge spring. Is characterized in that: The spring load characteristic line to which the shock absorbing spring is added is within the range of the suction force characteristic curve before the shock absorbing spring is extended from the hinge spring, so that even when the shock absorbing spring is added, the operating voltage of the electromagnetic relay is increased.

The spring load characteristic R2 in the stroke S2 is a load characteristic obtained by adding the resistance of the contact terminal plate 16 to the load characteristic of the contact spring 15, and is a straight line having a steep slope. The spring load characteristic R3 in the stroke S3 is obtained by adding the load characteristic of the shock absorbing spring 19 to the sum of the load characteristic of the contact spring 15 and the drag of the contact terminal plate 16, and is a straight line having a steeper slope.
When there is no impact buffer spring 19, the spring load characteristic R2 is extended as shown by the broken line.

When a spring load characteristic line is drawn on a graph with the spring load as the vertical axis, the spring load characteristic line to which the shock absorbing spring is added is within the range of the suction force characteristic curve before the shock absorbing spring is extended from the hinge spring. Therefore, even if an impact buffer spring is added, the sensing voltage of the electromagnetic relay does not increase.
