ABSTRACT OF THE DISCLOSURE In the housing of an electromagnetic switching apparatus including a magnet coil and switching and non-switching magnet parts disposed within the housing, and at least one damping compression spring for biasing the non-switching magnet part in one direction in the housing, the spring having a plurality of turns of the same diameter and one end turn having a diameter greater than that of the plurality of turns for securing the spring in the housing, the improvement comprising hook-shaped projection members disposed within the housing about the periphery of the compression spring. The pro- jection members are spaced apart from each other along a diameter of the spring by a distance which is greater than the diameter of the plurality of turns thereof but less than the diameter of the end turn. The plurality of turns of the spring are axially movable between the projection members while the end turn of the spring is engaged by the members. The compression spring is thus axially movably secured in the housing of the switching apparatus.
