<p>The extractor (1) has a stainless steel bell (2) defining two support points and supported against a surface corresponding to a shuttered wall (300) peripheral to an electric case (200), where the case exposes one of surfaces of the wall through an opening of a housing in which a magnet (100) is arranged. A threaded rod (3) is integrated to the bell and cooperates with an axial female thread (110) of the magnet. The rod has a nut (4) for displacing the rod with respect to the bell along an axis perpendicular to a support plane defining the support points.</p> |
