Electrical contact is a device that allows for the establishment or interruption of an electric current. They come in a wide variety of sizes and shapes and can accommodate a wide range of contact forces and spring rates. There are two main categories of electrical contacts: spring-loaded and pressure.

Spring-loaded contacts utilize a spring to provide the necessary force to form a connection between two surfaces. These are usually found in relays and switches. The spring rate of the contact is determined by the spring material and the geometry of the contact. The contact force must be great enough to ensure that the current is reliably transferred between the two surfaces. Higher spring rates are recommended for higher current applications.

Pressure contacts use a flat surface to create a mechanical connection between two surfaces. This is achieved through the use of a contact material with a high elastic modulus. The contact material is generally a metal, such as steel, that is highly corrosion-resistant. The contact force of a pressure contact depends on the amount of pressure applied by the user. Pressure contacts are typically used for low current applications. They are also used in applications where the contact surfaces may become corroded or oxidized over time.

Both types of contacts are used in a variety of applications, from automotive to consumer electronics. They are particularly useful in applications where reliability is a primary concern, as they provide a means for establishing or interrupting a current in situations where other types of contact may fail. They are also used to provide protection from surges and other electrical hazards, as they can act as an effective barrier against the flow of current.

Understanding the types of contacts available, their features, and their applicable use cases allow engineers and designers to make informed and accurate decisions when constructing or repairing any electrical system.
