Arcs are prevented as electrical connectors are unmated by including a long and a short contact in an electrical connector with both contacts being connected along the same line between an electrical source and a load. The short contact comprises the lower resistance path between the source and the load and so carries most of the current when the connectors are fully mated. An electronic component, such as an FET or a positive temperature coefficient resistor is connected to the long contact. As the short contact is disconnected, the electronic component initially carries sufficient current to prevent arcing at the short contact. Current through the electronic component decays rapidly so that when the long contact is subsequently disconnected, the electrical energy in the short contact is reduced below an arcing threshold.
