Electrical contact resistance (ECR, or simply contact resistance) is resistance to the flow of electric current caused by incomplete contact of the surfaces through which the current is flowing, and by films or oxide layers on the contacting surfaces. It occurs at electrical connections such as switches, connectors, breakers, contacts, and measurement probes. Contact resistance values are typically small (in the microohm to milliohm range).
Electrical contact is an important issue to high power microwave sources, pulsed power systems, field emitters, thin film devices and integrated circuits, interconnects, …

An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. Each contact is a piece of electrically conductive material, typically metal. When a pair of contacts touch, they can pass an electrical current with a certain contact resistance, dependent on surface structure, surface chemistry and contact time; when the pair is separated by an
The promise to impact contemporary applications has sparked great interest in the study of organic electronic and optoelectronic devices. The rich chemistry of organic …
The term Synchronization, relating to AC load switching, is used several times in this application note. In this context, synchronization is operation of a relay such that the contacts make or break (or both) at the same point on the load supply voltage waveform, or primarily at the same …
As an electrochemical characterization method, electrochemical impedance spectroscopy (EIS) [29], [30] is a potentially effective tool to evaluate contact states in working ASSLBs [31], [32], …
All About Contactors. When a relay is used to switch a large amount of electrical power through its contacts, it is designated by a special name: contactor ntactors typically have multiple …
The Electrical Contact Resistance at a metal to metal contact is primarily governed by: surface structure; mechanical load; The surface structure can be further …
