- a diameter of the electrical connection wire is greater than a diameter of the enameled wire. More preferably, a width of the recess, in which the electrical connection wire is arranged, equal to a diameter of the electrical connection wire. This will allows a secure cold contact between the electrical connection wire and the contact element. Furthermore, this ensures that the electrical connection wire can clamp in the recess, so that no additional means for fixing the electrical connection wire in the recess are necessary.
