Understanding the Principles and Applications of Electrical Contact Assemblies

Electrical contact assemblies are important in creating a wide range of products and components used in electrical devices. Let’s take a look at what exactly they are, and how they work.

The Basics of Electrical Contacts

An electrical contact is a component found in an electrical circuit that helps to complete it and allow for electrical current to successfully flow from one point to another. These electrical contact components occur in switches, connectors, circuit breakers, and relays, and they can be formed out of a range of materials depending on how well those materials both successfully conduct electricity and resist corrosion over time. The materials used in electrical contacts are also often chosen related to how affordable they are and how cost effective they are over time.

Electrical Contact Assemblies

Creating these small parts and components is just one phase of the process. Some companies also offer to help assemble these parts into a specific device, taking a set design, interpreting it, and putting into action the needs of a design plan according to what electrical contacts are needed and where. These assembly services can also involve a company partnering with an assembly group in order to have them manufacture electrical contacts that meet certain custom specifications.

Types of Electrical Contacts

These conductive parts can get pretty specialized. Buttons, rivets, various conductive surface features, and an array of refractory contacts are used to make up electrical contacts. They can be made from silver tin oxide, copper tungsten, silver graphite, and a wide range of other alloys that can accommodate different needs.

Electrical contact assemblies are incredibly important in the design and manufacturing of a wide range of electronics. These tiny conductive parts make the most everyday tools we use possible, from a television remote to a light switch to our cell phones. The next time you flip that switch or turn that knob, think about the tiny parts that are all working together to connect that circuit and make it work for you.
