Door latch for a domestic electrical appliance and method for mounting such a door latch

A door latch for a domestic electrical appliance, comprising a latch module comprising:

• a mouthpiece which delimits an insertion opening for a closing member which enters the insertion opening on closing of a door of the domestic appliance;
• a first recess beneath a first edge region of the mouthpiece;
• and
• a second recess beneath a second edge region of the mouthpiece located diametrically opposite the first edge region beyond the insertion opening,
• wherein the first and the second edge region of the mouthpiece define a first positioning plane and the first and the second recess are configured for engagement by opposing opening edges of a mounting opening formed in a mounting wall of the domestic appliance,
• wherein the latch module has stationary support points for supporting the latch module on a wall underside of the mounting wall, wherein the stationary support points lie in a second positioning plane located at a distance beneath the first positioning plane and parallel thereto and—as seen in a direction from the second edge region to the first edge region of the mouthpiece—are arranged on the other side of the second recess and at least partially also on the other side of the first recess,
• wherein the second recess has a region of smaller depth between the two positioning planes and a region of greater depth beneath the second positioning plane,
• wherein the latch module has at least one resiliently movable support point, projecting into the space between the two positioning planes, for supporting the latch module on the wall underside of the mounting wall,
• wherein the resiliently movable support point—as seen in the direction from the second edge region to the first edge region of the mouthpiece—lies in front of a mid-point between the two recesses,
• wherein a second lateral wall sub-portion forms a pocket base of an insertion pocket which allows an opening edge of a mounting opening formed in a mounting wall of the domestic appliance to be inserted into the insertion pocket, wherein an upper pocket wall of the insertion pocket is formed by a wall step of a second lateral wall which forms a transition between a first and the second lateral wall sub-portion, and a lower pocket wall of the insertion pocket is formed by a third lateral wall sub-portion of the second lateral wall which adjoins the second lateral wall sub-portion therebeneath and extends obliquely outwards and downwards,
• the door latch comprising a first support surface and a second support surface, wherein the second support surface extends between first and second opposed ends, wherein the second end defines a support edge, wherein the first support surface and the first end are arranged offset in a direction toward the first collar portion in relation to the mid-point.
