Patent ID: 8786388

Claim:
An electromagnetic switch ( 16 ) for a starting device ( 10 ), comprising two contacts ( 180 , 181 ) that are electroconductively interconnected by a mobile contact link ( 184 ) that moves along a movement axis of a switching pin ( 177 ) and has a contact edge ( 279 ) and a central flat section ( 270 ) with a hole ( 226 ), wherein at least one of the two contacts ( 180 , 181 ) comprises a contact surface ( 300 ) fixed to a contact pin ( 150 , 151 ) having a longitudinal axis ( 312 ) that is a central axis of the contact pin ( 150 , 151 ), characterized in that the contact surface ( 300 ) has fluting in the shape of an annular fluting ( 310 ) and an outer flat section ( 276 ) of the contact link ( 184 ) glides or rubs along a surface ( 420 ) of a wave-like contour ( 303 ) of the annular fluting ( 310 ) during a switching operation or, respectively, when providing contact, and wherein the outer flat section ( 276 ) has a face ( 318 ) that points toward the contact surface ( 300 ), and wherein during a switching operation there is a current passage area, with the longitudinal axis ( 312 ) being disposed between the current passage area and the movement axis of the switching pin ( 177 ), and with the current passage area being disposed between the contact edge ( 279 ) and the longitudinal axis ( 312 ), and further wherein an angle (β) of greater than 90 degrees exists between the face ( 318 ) and the longitudinal axis ( 312 ) and points toward a central axis ( 315 ) of the switch ( 16 ).
