Abstract
A jack has first and second jack ports, first and second contacts, and a switch having a full, half, and no normal positions. In the full normal position, the switch couples the first and second contacts together when no plug is inserted into either the first or second jack port, and the switch conditions the jack so that, when a plug is inserted into either the first or second jack port, the coupling between the first and second contacts is broken, the first contact is coupled to the plug if the plug is in the first jack port, and the second contact is coupled to the plug if the plug is in the second jack port. In the half normal position, the jack operates in the same way except that, when a plug is inserted into the second jack port, the coupling between the first and second contacts is maintained. In the no normal position, there is no coupling between the first and second contacts whether or not a plug is inserted into either the first jack port or the second jack port.
