Contact Interfaces – How They Work

It may be obvious that any component added to a circuit path makes a contribution to the overall resistance of that path. This is certainly true of a set of mating connectors having a separable interface. However, the elements making up that contribution may not be so obvious. Each of the mating connectors includes three different regions that contribute to resistance. The portion of each connector that physically touches the other is the region of Interface Resistance.
