ABSTRACT:
Connector 10 mountable to a mother board for mating with a daughter card (80,90) at a card-receiving slot (14). Connector (10) includes at least two key-receiving sites (30a,30b) along the length of the card-receiving slot (14), and a pair of switching contacts (40) at each site that are normally in engagement with each other, completing an indicator circuit of the mother board. A key member (50) is affixable to the connector at a selected one of the key-receiving sites (30a,30b) and includes an actuator arm (58) that disengages the switching contacts (40), breaking the circuit. The key member (50) prevents insertion of a daughter card (90) that is not programmed by having a notch (82) at the corresponding location.
