Interface for electrically contacting a printed circuit board which is accommodated in a housing, wherein the interface by means of a first and a second interface is configured as a double-sided and/or two-part interface (1, 2), having the following features: the first interface has as a printed circuit board contact at least one first contact element for electrically contacting at least one terminal of the printed circuit board; the second interface has at least one second contact element; the second interface is configured so as to correspond with the first interface and designed for disposal in a locationally fixed manner and/or fixation on an opening of the housing in such a manner that the first and the second contact element are brought into contact with one another, wherein the second contact element provides a terminal which is able to be contacted from outside the housing; wherein the second interface is provided by means of a second insulating member which is configured in a form-fitting manner with the opening of the housing, and in which the second contact element is accommodated so as to be locationally fixed in such a manner that one end of the second contact element extends into the interior of the housing, and one end of the second contact element provides the terminal which is contactable from outside the housing; characterized in that the second insulating member is configured in such a manner and/or is disposed on the housing in such a manner, and/or has an internal contour which interacts in a form-fitting manner with a contour of the second contact element in such a manner, that plug-in and/or extraction forces acting on the terminal contactable from outside the housing are absorbed by the second insulating member of the second interface and/or by the housing; and wherein the first contact element is disposed and configured to correspond to the second contact element; wherein the first contact element has a socket having an axis, and the second contact element is formed at least on the inside of the housing as a pin contact, and wherein the pin contact is inserted into the socket, and the first contact element is a stamped-bent contact having a flat central portion and having a curved portion which adjoins the central portion and by means of which the socket is provided; wherein at least one foot on a first side of the central portion of the stamped-bent contact extends in a first direction, wherein the foot is provided for connecting to the terminal of the printed circuit board; and the socket having the axis on a second side of the central portion is configured by means of a bend in the stamped-bent contact, said socket being provided for connecting to the pin contact of the second interface. the first interface has as a printed circuit board contact at least one first contact element for electrically contacting at least one terminal of the printed circuit board;
