Abstract: The electrical switching apparatus includes a housing (10), a coil (20) arranged in the housing (10), at least two switch terminals (35,50,60) arranged in the housing (10), a magnetic angle piece (30) in the housing (10) including a core (32) for the coil (20) and an armature (42) resiliently mounted on the magnetic angle piece (30) for making electrical contact between two switch terminals (35,50,60).

Abstract: In order to define more precisely the pivot line (25) on which the armature (17) swings about the magnet yoke (12) at its line of contact therewith, the armature restoring spring (28) is made of spring wire (29) bent into meander shape. One end of it is attached to the magnet yoke and the other to an extension (31) of the armature that extends across the pivot line. A spring clip (34) is snapped over the restoring spring and onto the sides of the magnet yoke pushes the restoring spring against the magnet yoke and opposes lengthwise shifting of the armature across the edge (32a) on which it is pivoted.

Abstract: Reduced base plate dimensions are provided for an electromagnetic relay of the kind having a flap type armature by disposing the core which carries a spool and the winding therein perpendicular to the base plate with its free end spaced from the base plate sufficiently for the armature to swing between the free end of the core and the base plate, while being hinged in a seat at one end of the armature provided in the magnet yoke. Support for the magnetic system of the relay, which like the base plate assembly is a preassembled unit is provided by anchoring portions (29) of the magnet yoke which lie against the armature seat and are so set in the base plate when the two subassemblies are put together, that the free end of the core is in the position described. A leaf spring carrying the switch contact as an aperture stamped out in it for centering the armature. The switching path connections are very short and various details are provided to simplify assembly and adjustment of the relay in mass production.
