  • Patent number: 6767232
    Abstract: An electrical card connector (100) includes an insulative housing (2), a number of terminals (6) received in the housing, a shell (3) shielding the housing, and a first and second switch contacts (41, 42) for write-protect and full insertion detection for an electrical card (7). The housing includes a pair of side walls and a receptacle portion. One of the side walls defines a first and a second slits for respectively receiving the first and the second switch contacts. The shell has a generally planar top wall (31) and a pad (33) extending downwardly from one side of the top wall. The first and the second contacts respectively include a first and a second spring portions (413, 423) extending into the receptacle portion of the housing. The electrical card, during being inserted into the receptacle portion, successively pushes the first and the second spring portion outwardly to electrically connect with the pad of the shell.
