Copper is not only the standard of conductivity, but also the world’s preferred conductor material. It is present in nearly all electrical contact applications, either in the material of the contacts ...

The Copper Development Association has released a book on how electrical contacts work and the various materials involved, and it is free to download. “The importance of electrical contacts has been ...

Wear in electrical contacts arises from the complex interplay between mechanical, thermal and electrical phenomena occurring at the interface of contacting surfaces. These interactions give rise to a ...

The sliding electrical contacts found in instrument quality slip rings must reliably conduct signals onto or off of rotating platforms. The signal quality is typically evaluated by measuring the noise ...

Columbia Engineering researchers have experimentally demonstrated for the first time that it is possible to electrically contact an atomically thin two-dimensional (2D) material only along its ...

We are living in the age of electronics. New cars won't run without a couple dozen engine and drivetrain sensors, not to mention the hundreds of electronic connections that make up the audio and ...

With the exception of proprietary interfaces requiring special connectors, most connector types and configurations haven’t changed significantly since their creation. For example, we still use the ...

Found in a multitude of devices, relays are simple electromechanical switches featuring an electromagnet, one or more electrical contacts, a movable iron armature that is attracted by the magnetic ...

On August 16, 2007, Master Electrician William Giffen, owner of CAMAND Electrical Services, Ottawa, Canada, and experienced 17-year veteran of electrical maintenance services, was testing secondary ...

Some engineers, as well as many non-engineers, might be unaware that electrical switches benefit from being lubricated. In fact, for many electrical switches, lubrication is required if they are going ...
