ABSTRACT:
A steering wheel assembly includes a horn switch in a horn pad. An insert is attached integrally to the backside of a pad cover to form the horn pad while defining a space therebetween. The insert is made of a hard electrical insulating material while the pad cover is made of a soft synthetic resin. A sheet member is disposed in the space between the insert and the pad cover. A resilient member such as a coil spring urges the sheet member toward the pad cover while supporting it movably in the space. A fixing frame made of a sheet metal secures the insert. A moving contact is arranged on the sheet member while a fixed contact is fitted on the fixing frame so as to face the moving contact. These contacts operate as switching elements.
