A SIM card connector includes a connector body. The connector body defines a receptacle channel that extends inwardly from the front. The receptacle channel further defines a first hole and a second hole. Pluralities of terminals mount in the middle of the connector body. A switch terminal mounts in the connector body. The switch terminal has a fixing portion received in the first hole and a contacting portion received in the second hole. The contacting portion forms an arced surface. The top of the arced surface is inserted into the second hole and protrudes above the top surface of the housing base in the receiving cavity.
