Electromagnetic relay with armature part convenient to insert

The invention discloses an electromagnetic relay with an armature part convenient to insert. The electromagnetic relay comprises a magnetic circuit part and a base. The magnetic circuit part comprises the armature part which is installed on the base through a rotary shaft. The armature part is provided with a first shaft hole. The base is provided with two supporting parts which are provided with second shaft holes. The armature part is matched between the two supporting parts and positioned on the base through match of the first and second shaft holes. Protruding bumps respectively extend outward on two side face of the armature part. Brackets are respectively arranged on the inner side surfaces opposite to the two supporting parts of the base. The rotary shaft is installed into the first and second shaft holes through match of the protruding bumps and the brackets. According to the structure, the rotary shaft in the armature part can be easily threaded to the shaft holes of the armature part through the sha
