An electrical connector (1) has a housing (10) receiving signal contacts (12) therein, a switch (14) for detecting full insertion of an electrical card (2), and a guide frame (13) supporting the card therein and slidably engaged with the housing. The switch includes a fixed contact (15) and a resilient contact (16), which are in contact with each other when the switch is in a normal position. The fixed contact has a contact piece (150) connected to a first switch trace (31) of a PCB (3). The resilient contact has a solder tab (161) connected to a second switch trace (30) of the PCB, and a spring arm (162) for contacting the contact piece. The guide frame has a wedge (136) for disengaging the spring arm from the contact piece when the card is fully inserted into the housing.
