Wireless connectivity specialist GradConn offers CH03-AJ with two switch options, customers may choose between normally open (standard) or normally closed (switch).

Some applications require a normally closed (NC) switch. The standard SIM card connector switch type is Normally Open (NO), contacts are open (circuit broken) until a SIM card is inserted and the circuit is closed. In the case of Normally Closed (NC) the circuit is closed until the SIM card is inserted, it then becomes open.
