ABSTRACT An electromagnetic relay is characterized in that a base of the relay is provided on a bottom surface thereof with through holes extending outwardly and projecting reference blocks to determine the reference positions for engagement of a coil assembly. A coil spool has flanges on both ends and these flanges are cut off in the shape substantially corresponding to the shape of the reference blocks. Projections are provided on one of the inner walls of the base or the flanges of the spool for engaging with the base when said coil assembly is inserted from above into the base. The base and the coil assembly are fixed with a sealant which is poured into the bottom surface of the base to creep through the holes of the base to eventually contact the lower part of the flanges and with the projections for engagement. The relay is easy to assemble and has stable characteristics under conditions of vibration or environmental fluctuations.
