An electrical socket contact (1) with

• a box-shaped base part (2) with four side walls,
• a rear connection part (3) for receiving a conductor wire,
• at least two opposed contact spring arms (7) integrated on the base part (2) on two side walls which are arranged over part lengths at a distance from one another bent towards one other and bent back at their free ends, characterised by at least one guide rail (8) which is offset in relation to the spring arms (7) and integrated on a periphery of the base part (2) and whose free end extends in the direction of the free end of the contact spring. arms (7), wherein the guide rail guides a contact pin along a plug axis and wherein the guide rail prevents an oblique introduction of the contact pin at an angle relative to the plug axis;
