ABSTRACT:
A set of horn switch assemblies are mounted on a base plate of a vehicle steering wheel and linked by two continuous electrical conductors that are electrically bridged to activate a horn. Each switch assembly includes an insulator base affixed to the base plate and a deflectable metal blade disposed atop the insulator base substantially parallel to the base plate. The metal blade is anchored to the insulator base at one end and deflectable toward the base plate at the other end. One electrical conductor is secured to the insulator base below and in contact with the anchored end of the metal blade, while the other electrical conductor is secured to the insulator base below and out of contact with the deflectable end of the metal blade. A driver air bag assembly deflects the metal blades to electrically bridge the two electrical conductors for activating the horn.
