Switch, Horn: Description: Description
A normally open floating-type horn switch and mounting plate (1) is secured to the back of the Driver AirBag (DAB) housing within the hub cavity of the steering wheel. The four sets of switch electrical contacts are each held open by a coiled spring and captured by a mounting screw (3) and E-clips arranged around the perimeter of the mounting plate. A switch wire harness joins the contacts in a parallel circuit to a connector (2) that is connected to the vehicle electrical system through a dedicated take out and connector of the steering wheel wire harness.
The stamped metal switch mounting plate has a mounting tab with a threaded insert (4) on each side, which is used to secure the DAB and floating horn switch assembly within the steering wheel hub cavity with a screw installed through each side of the steering wheel armature. The floating horn switch contacts, mounting plate and wire harness are serviced as a unit. If the horn switch is ineffective or damaged, the entire floating horn switch assembly must be replaced.
