An electromagnetic relay comprising:
- an electromagnet assembly (X) having a core (4);
- a bobbin (1) for inserting said core thereinto;
- a yoke (5) fixed to an end of said core;
- a hinge spring (6);
- an armature (7) coupled via said hinge spring to said yoke and coupled to the other end of said core;
- and
- a base block assembly (Y) having a base block (8) and a contact spring assembly (9, 10, 11) including a movable contact (9a) and a stationary contact (10a, 11a) adhered to said base block,
- wherein an adjustment of said armature to said contact spring assembly is carried out prior to fixing an adjustment of a position of said electromagnet assembly relative to said base block.
