An electrical contact (22) includes a first beam (28), a second beam (29), and a receiving cavity (20) defined between the first beam and the second beam. The first beam has a first mating face (281) facing to the receiving cavity, and the second beam has a second mating face (291) facing to the receiving cavity. The first mating face cooperates with the second mating face to form a first mating area to clamp a first area of a mating contact. The first beam has a third mating face (282). The third mating face forms a second mating area facing sidewardly to abut against a second area of a mating contact. The first beam projects sidewardly to form the third mating face.
