Summary:Electrical connectors 40, 104 including contact terminals that can be unmat ed without previously disconnecting power include main contacts 12, 112 and auxiliary contacts 16, 130 that are shunted by a positive temperature coefficient (PTC ) resistor 6, 140 located between the main and auxiliary contact. The main contact 12, 112 will be disconnected first and the auxiliary contact 16, 130 can be longer than t he main contact 12, 112. Arcing will not occur at the mating end of the main contact 12, 112, because the current will be shunted to the still connected longer auxiliary contact 16, 130. I2R heating will increase the resistance in the PTC resistor 6, 140, so when the auxiliary contact 16, 130 is disconnected, current will be below the arcing threshold. Multiple latches 54 A,B and 60 A,B or 180 and 196 permit only discontinuo us mating of electrical connectors, so that the connectors can be disconnected without arcing for a range of currents.
