A clock spring has connectors that link the steering wheel to the rest of the vehicle's system. Along with the horn, every steering wheel has numerous buttons on it. Sometimes these buttons are on the sides of the steering wheel, and other times, they are on the front.
Generally, they control the cruise control, radio volume, and numerous other functions. The clock spring allows them to connect to the rest of the vehicle. Every clock spring comes with multiple connectors that connect to these buttons, as well as the horn and the airbag, and conductors on the inside of the clock spring allow it to rotate and transmit power.
The clock spring will no longer work if the conductors ever break.
