<p>D-22042 -17- Electromagnetically operated contactor or relay in which the stationary magnetic core and operating coil are mounted in a base section and the movable armature and the switching elements are mounted in a main frame section. With the two sections assembled together the pole face structures of the stationary core abut reference surfaces in the main frame section. When the operating coil is energized, the armature moves into contact with the pole faces of the stationary core. Thus, since the reference surfaces in the main frame section determine the position of the stationary core pole faces and hence the position of the armature when the core is energized, the positions of all movable elements are determined solely by dimensions of the main frame section independently of the base section.</p> |
