An electromagnetic relay has a plate-like core wound with a coil which is formed as a whole in the shape of a letter U, and is provided with projections respectively on both sides of the ends. A permanent magnet is in contact with the core. A platelike armature which can be moved in a seesaw manner so as to cause both ends thereof to contact with or separate from both ends of the core is provided. Movable contact springs move in accordance with the armature in the seesaw movement. A base is provided with stationary contacts with which movable contacts of the movable contact springs cooperate in the seesaw movement. The armature ends pass between the projections provided on both sides of the core ends when the armature ends engage or disengage from the core ends. The relay has a flat configuration thereby reducing the packaging height.
