An electromagnetic relay includes a base, a spool provided on the base, a coil wound on the spool, a yoke inserted into a hole formed in the spool, an armature movably disposed on the base, a movable contact fixed on the base, a static contact fixed on the base, a driving member connected between the armature and the movable contact, and an elastic pressing member fixed on the base. The elastic pressing member is pressed against an outer side of the armature so as to position the armature on the base and provide an auxiliary thrust to the armature.

An electromagnetic relay includes a base, a casing, a coil, a movable contact piece and two fixed contact pieces. Each of the fixed contact pieces includes a plate-shaped base. A portion of one side of the plate-shaped base extends outward and is bent to form a fixed contact fixing part. The fixed contacts are arranged on the fixed contact fixing part, and an abdicating through hole is defined in the base. The plate-shaped bases of the fixed contact pieces are respectively connected to an outer side surface of the base and spaced from each other. Each of the fixed contact fixing parts protrudes through the abdicating through hole and located between the base and the casing. Each of the fixed contacts faces to the movable contact on the movable contact piece, and a portion of the plate-shaped base on the fixed contact piece protrudes out of the casing to form a connecting part.
