Abstract: An electromagnetic relay comprising a base of insulating material carrying stationary and movable contacts and output lugs, and a motor assembly, the latter comprising a right-angled yoke, a core with its coil, crimped to the inner face of a first one of the two flanges of the right-angled yoke, and an armature pivotally mounted to the free end of the second flange of said yoke and having bent arms operable to actuate the movable contacts when the base is fixed to the outer face the second flange and the coil is energized. The coil has a spool or frame with at least one end flange provided with metal tongues for coil connection extending towards the base and passing through apertures in the second flange of the yoke, said tongues resiliently engaging inner ends of associated ones of said output lugs.
