Enables airbag deployment
The primary function of the clock spring is to maintain a constant electrical connection to the driver's side airbag. In the event of a collision, this ensures the airbag receives the signal to deploy, which is a vital safety feature.

Powers steering wheel controls
Modern vehicles feature a variety of controls on the steering wheel, such as buttons for the radio, cruise control, and phone connectivity. The clock spring provides the necessary power and signal paths, allowing these controls to function seamlessly even while the wheel is being turned.

Maintains horn functionality
The horn is an important safety feature that is also powered through the clock spring. The clock spring ensures that the horn works reliably in any steering wheel position, which is essential for signaling other drivers.

Allows for a continuously rotating steering wheel
The coiled, ribbon-style design of the clock spring allows it to extend and retract as the steering wheel turns. This prevents the electrical wires from becoming tangled, twisted, or broken, which would otherwise occur with a traditional straight-wire connection.

Ensures system integrity
By preventing the electrical connections from being severed, the clock spring maintains the integrity of the vehicle's electrical system for all functions located on the steering wheel. This is a far more robust and reliable design than simple slip rings and brushes used in older vehicles.

Facilitates integration with advanced systems
In many vehicles, the clock spring includes a steering angle sensor, which detects how many degrees the steering wheel is turned. This sensor sends information to the vehicle's computer and is a key component for modern safety features like traction control and stability control.
