A memory card connector includes an insulating housing defining conductive terminal grooves and a switch terminal groove. A metallic shell coupling with the insulating housing to form a card cavity therebetween has a top section and two side sections. The front of a top surface of one side section extends and inclines to the front of the top section to form an anti-mismating portion connecting with the front of the top section to form an inclined corner at the front of the metallic shell. One side section extends rearward to form a touching portion protruding toward the inner of the card cavity. Conductive terminals received in the conductive terminal grooves have a base portion, a soldering portion and a contacting portion. A switch terminal assembled in the switch terminal groove has a main body extending rearward to form a resilient arm received in the card cavity. The resilient arm defines a contacting projection facing the touching portion and a pressing portion facing the inner of the card cavity.
