Embodiment Construction
[0032] Figure 1a )with Figure 1b ) schematically shows the connection mode of the plunger 10 and the armature 12 in the prior art. refer to Figure 1a )with Figure 1b ), the plunger 10 is guided to move through the opening 13 of the armature 12 from below along the longitudinal axis L of the plunger 10 until the lower shoulder 14 of the plunger 10 fits on the armature 12 . Subsequently, the retaining washer 16 is introduced into the armature 12 from above and slid onto the plunger 10 until the retaining washer 16 rests on the upper shoulder 18 of the plunger 10 . The retaining washer 16 is dimensioned such that it protrudes radially beyond the opening 13 of the armature 12 . Subsequently, a punching tool (not shown) is introduced into the armature 12 from above, whereupon the plunger 10 is deformed so that the retaining washer 16 is fastened on the plunger 10 with a positive fit. The plunger 10 assumes a mushroom-like shape due to deformation. The position of the plunge...
