Abstract
Abstract A press-in contact to be pressed into a throughplated hole of a printed circuit board includes a contact spring or a contact pin, a middle shaft portion connected to the contact spring or pin, and a connecting pin forming an extension of the middle shaft portion. The contact spring or the contact pin has in the transition area to the shaft portion a press-in shoulder. The shaft portion is provided with a slot-shaped opening whose sides are formed by legs. Each end of the slot-shaped opening has an approximately parabolic configuration. The slot-shaped opening is conically shaped and the end of the slot-shaped opening facing the contact spring or the contact pin extends into the area of the contact spring or the contact pin.
