A selectable compatibility plug has a substantially hollow housing member and a plurality of contact members extending from a cable connection end to a connector end. A movable circuit member is contained in the housing for translational movement, the circuit members having circuit components on a surface thereof that is in contact with the contact members. Actuator means for moving the circuit member from a first position to a second position is mounted to the circuit member and adapted to be actuated when the plug is inserted in a low performance jack to cause the contact members to contact certain ones of the circuit elements.
