ABSTRACT:
An electrical connection set-up for manufacturing an ignition coil is provided, which includes, on the side of the low-voltage outlet, a contact spring which is installed by being lifted over corresponding secondary windings without touching them and which then snaps into place due to spring-like form or support, while elements provided on the contact spring break through an insulating layer surrounding the secondary winding, thus establishing the electrical connection without the use of thermal methods.
