Abstract

The relay incorporates a coil body (2) with flanges (21,22) and a winding (23), a rod-shaped core (31), an angle yoke (33), with a leg (34) joined to the end (31a) of the core and the other leg (35) parallel to the core next to the winding (23), and a movable armature (4) actuating a contact spring (41). The yoke leg (34) in the flange (21) is secured against axial motion and pivoting by means of holding elements, while the core (31) is joined to the side surface of the yoke leg only by its end face (31). The yoke legs (934) are pushed (drawer fashion) into the grooves of the coil flange (21). The core (31) is joined to the yoke leg by means of hard soldering. Alternatively, it is joined to the yoke leg by means of welding. There are two coil bodies (2) (each with a winding, a core, a yoke and an armature arranged in a mirror-image fashion. The two coil bodies are made as a single component with a central double flange and two end flanges. The coil body is mounted on a base (1) incorporating at least one fixed contact carrier (14,15), and at least one spring carrier (17) for each contact spring (41).
