Electromagnetic relay

An electromagnetic relay, comprising:

• a base, an abdicating through hole is defined in the base;
• a bobbin connected with the base;
• a yoke connected with the bobbin;
• a casing connected with the base;
• a coil wound on a bobbin, the bobbin being between the base and the casing, the bobbin having a center hole;
• a movable contact piece having a first end connected to the yoke and a second end connected with an armature and a plurality of movable contacts;
• a core installed in the center hole of the bobbin, one end of the core facing to the armature, and the other end of the core being connected to the yoke directly or connected to the yoke through a magnetic steel;
• and
• two fixed contact pieces, each of the fixed contact pieces comprises 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, fixed contacts are arranged on the fixed contact fixing part, 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 a movable contact of the plurality of movable contacts 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.
