What is Ring Terminal?

A ring terminal, also known as a ring connector or ring lug, is a type of electrical connector that is typically used to attach wires to posts or studs on electrical components such as switches, circuit breakers, terminals, or other devices. It consists of a circular-shaped metal or insulated ring with a hole in the center that allows a screw or bolt to pass through it. The wire is inserted into the ring terminal and then secured by tightening the screw or bolt, creating a secure electrical connection.

Ring terminals are available in various sizes to accommodate different wire gauges and stud sizes. They are commonly used in automotive, marine, industrial, and electrical wiring applications where secure and reliable connections are essential for safety and proper functionality.
