Electromagnetic relay
 An electromagnetic relay of a flat configuration which can switch electric contacts by producing a seesaw movement of an armature. The relay has an armature assembly having moveable contacts, a coil assembly implemented as a coil spool having a core and wound with a coil, and an insulating base supporting stationay contacts, coil terminals, and connection terminals. The coil assembly is built in the base by affixing the coil terminals of the coil assembly to coil terminals of the base, and then the base is molded to cover the whole coil assembly except for both ends of the core and a bore for receiving a permanent magnet. The base, therefore, fully spaces apart the joints of the coil terminals and the contacts and spaces apart the coil and the contacts.
