摘要： The invention relates to an electromagnetic switch (16) for a starting device (10), comprising two contacts (180, 181) that are electroconductively interconnected by a mobile contact bridge (184). At least one of the two contacts (180, 181) preferably comprises a contact surface (300) fixed to a contact stud (150, 151). According to the invention, a) the contact surface (300) is at least essentially flat, and an edge (279) of the contact bridge (184), providing electrical contact between the contact bridge (184) and the contact (180, 181), is arranged in such a way that, once it has come into contact with the contact surface (300), it enables a linear contact between the contact (189, 181) and the contact bridge (184), or b) the contact surface (300) comprises bumps lying essentially in one plane, and an edge (279) of the contact bridge (184), providing electrical contact between the contact bridge (184) and the contact (180, 181), is arranged in such a way that, once it comes into contact with the contact surface (300), it enables essentially a multiple-point contact between the contact (180, 181) and the contact bridge (184), or c) a surface (318) of the contact bridge (184), oriented towards the contact (180, 181), and a longitudinal axis (312) of the contact stud (150, 151), form an angle (ß) oriented towards a central axis (315) of the switch (16) and larger than 90°, or d) a surface (318) of the contact bridge (184), oriented towards the contact (180, 181), and a longitudinal axis (312) of the contact stud (150, 151), form an angle (ß) which is radially outwardly oriented towards a central axis (315) of the switch (16) and is larger than 90°. The invention also relates to a method for switching an electromagnetic switch, preferably a starting device (10), comprising two contacts (180, 181) that are connected by a mobile contact bridge (184). When the contact bridge (184) is contacted by at least one of the two contacts (180, 181), a rubbing movement is generated between the contact bridge (184) and the contact surface (300) of the contact (180, 181).

摘要： A starting apparatus having an electromagnetic switch (16), having two contacts (180, 181), which can be electrically conductively connected to one another by means of a moving contact link (184), wherein at least one of the two contacts (180, 181) has a contact surface (300) which is connected to a contact bolt (150, 151), wherein the contact surface (300) has projections with a corrugated contour (303), characterized in that they essentially lie on a plane and the contact link (184) has an outer flat section (276), wherein, in one switch position, the outer flat section (276) of the contact link (184) slides or rubs on a section of the corrugated contour (303), whose surface faces away from a central axis (315) of the switch (16), wherein the corrugated contour (303) is part of an annular groove system (310), and a current transmission surface (500) between the surface (318) and the contact surface (300) is in the form of a sickle. A method for switching an electromagnetic switch of a starting apparatus (10), having two contacts (180, 181) which are electrically conductively connected to one another by means of a moving contact link (184), wherein, when the contact link (184) makes contact with at least one of the two contacts (180, 181), a rubbing movement acts between the contact link (184) and a contact surface (300) of the at least one contact (180, 181), wherein the contact surface (300) has projections which essentially lie on a plane, and the contact link (184) has an outer flat section (276), wherein, in one switch position, the outer flat section (276) of the contact link (184) slides or rubs on a section of the corrugated contour (303) which faces away from a central axis (315) of the switch (16), wherein, when sliding, a surface (318) adjusts a current transmission surface (500), which is in the form of a sickle, via the contact surface (300).
