1. A connector comprising:
a tongue;
a plurality of contacts having contacting surfaces on the tongue, each of the plurality of contacts to form physical and electrical connections with a corresponding contact in a corresponding connector when the connector is mated with the corresponding connector;
a liquid-detect contact to remain disconnected from any contact in the corresponding connector when the connector is mated with the corresponding connector;
a connection detection contact to detect a connection to the corresponding connector, the connection detection contact selectively coupled to a pull-down resistor; and
a liquid-detect circuit coupled to the liquid-detect contact, wherein the liquid-detect circuit uses the liquid-detect contact to determine a presence of liquid on the tongue, and when a presence of a liquid on the tongue is detected, the connection detection contact is disconnected from the pull-down resistor.
