Clockspring

A clockspring (also referred to as spiral spring or spiral cable)[1] is a type of spring often found in automobiles, that stores energy on a rotating axis. Clocksprings generally consist of a flat multicore cable wound in a spiral shape similar to a clock spring, hence the name,[2] but the name is also given to devices fulfilling the same purpose but which use spring-loaded brushes contacting concentric slip rings.[3]

In automotive systems

In vehicle steering systems a clock spring or clockspring is a spiral-wound special rotary electrical conductor which allows a vehicle's steering wheel to turn while still making an electrical connection between the steering wheel airbag and/or the vehicle's horn and other devices and the vehicle's electrical systems. The clockspring is located between the steering wheel and the steering column.
