An electromagnetic relay is disclosed comprising within its coil bobbin a magnetic core, the ends of which extend substantially at right angles to the longitudinal axis of the bobbin so as to form pole shoes projecting from the coil bobbin and having mutually aligned pole faces and further comprising an armature which is disposed externally of the coil bobbin between the pole shoes of the magnet core and which is pivotally mounted for rotation about one of its centroid axes, said one axis extending perpendicularly to the longitudinal axis of the bobbin. Contact terminals are disposed on both sides of the longitudinal axis of the coil and are positively located by embedment in a contact carrier, the coil bobbin and the contact carrier extending substantially over the entire length of the coil bobbin and being provided with engaging means for the mutual positioning and retaining of the contact carrier and coil bobbin. The contact terminals have associated therewith prelocated contact springs arranged within the relay, the forces exerted by the contact springs interacting through the armature and including bearing means for the armature provided substantially centrally of the coil between the pole shoes.
