About Auxiliary Contacts

Auxiliary Contacts, also known as aux contacts, are components used in contactors and motor starters to control the flow of electricity. They are a type of contactor or contact block that can open and close a circuit, thus allowing electricity to pass through it.

Types of Auxiliary Contacts

Auxiliary Contacts come in many different types depending on the job they are intended for. Some auxiliary contact blocks may be built into a contactor, while others may be separate from the contactor itself. In addition, auxiliary contacts may have different configurations such as normally open or normally closed depending on the application.

How Auxiliary Contacts are Made

Auxiliary Contacts are typically made from materials such as copper alloy, brass alloy, stainless steel alloy and carbon steel. The construction process involves various technologies such as welding, riveting and crimping to ensure that each part is securely fastened together.

Industries that use Auxiliary Contacts

Auxiliary contacts are used in many industries including manufacturing plants, industrial facilities and electrical engineering projects. Professionals in these fields use them to control motors and other electrical systems by opening or closing circuits when needed.
