ABSTRACT:
This invention concerns a plug device with phase selection, especially as a plug connector for track lights, and the problem is addressed of making such a plug device economically, with the smallest structural dimensions, and with the lowest internal resistances. This is achieved by a contact unit consisting of a connecting contact and a contact arm, which can be deformed by torsion and/or bending to contact different internal contact tap surfaces in the device.
