The electromagnetic relay (19) has a motor assembly (44) with a bobbin (50) secured to a frame (46). A core (56) disposed within the bobbin (50) except for a core end (60) which extends from the bobbin (50). An armature end (59) magnetically engages the core end (60) when the coil (54) is energized. An actuator (62) engages the armature (58) and a plurality of movable blade assemblies (50). The movable blade assembly (50) is comprised of a movable blade (68) ultrasonically welded onto a center contact terminal (51). A normally open blade (55) is positioned relatively parallel to a movable blade (68). The normally open blade (55) is ultrasonically welded onto a normally open terminal (69) to form a normally open contact assembly (71). A normally closed contact assembly (52) comprised of a third contact rivet (52a) and a normally closed terminal (52b). A normally closed contact assembly (52) is vertically positioned with respect to the movable blade (68) so that the normally closed contact assembly (52) is in contact with the movable blade assembly (50) when the movable blade (68) is not being acted upon by the actuator (62).
