ABSTRACT:
The metal housing of the case of a contactor includes an annular rib extending continuously opposite the cylindrical periphery of the main stationary core, the rib having an internal diameter respectively greater than that of the ferrule and smaller than that of the housing, so as to ensure the locking of the different parts of the case and the crimping of the housing on the stationary magnet following local deformations exerted on the reduced diameter of the swaged part defining the rib.
