Electric light bulb holder has circular magnetic surface that ensures unity of two parts at lower end of upper part and four magnets arranged all around cone shaped upper pad of lower part

摘要

A second contact (10) forms a ring below a tip of a cone on a lower part of the frame. The latter has a corresponding counter ring (4) in the cone shaped cutout in its upper part. A circular magnetic surface (5) ensures the unity of the two parts at the lower end of the upper part. Four magnets (6) are arranged all around the cone shaped upper pad of the lower part.
