Abstract
The electromagnetic switching device, especially contactor consists of an electromagnet (2) fastened in its housing, with a core (2) and an armature (14). Mounted on the core (2) is a magnet coil (17) carrying the coil assembly (7) and coil terminal parts (8) protruding only in one direction. The coil assembly (7) can be installed into the housing in two 180.degree. offset positions, around the winding axis of the magnet coil (17). The electromagnetic switching device can be used with unchanged inscription at 180.degree. offset coil terminal parts (8).
Claims2
An electromagnetic switching device comprising:
- a housing;
- a core fastened within the housing, the core defining a winding axis;
- a generally symmetrical coil assembly disposed about the winding axis, the coil assembly shaped so as to fit within the housing in two positions offset by 180.degree. with respect to the winding axis;
- and at least two terminal parts coupled to the coil assembly, the terminal parts protruding in one direction from the housing.
