US Patent 7118125 Horn switch assembly for vehicles

Disclosed herein is a horn switch assembly for vehicles. The horn switch assembly comprising studs, elastic members, a horn plate, a movable switch terminal, and a stationary switch terminal, is disposed between an airbag housing mounted in a steering wheel and an airbag cover vertically slidably attached to the airbag housing. Each of the elastic members has a relatively small spring constant since the elastic members of the horn switch assembly support only the airbag cover formed of a plastic material easily broken when an airbag is expanded, whereby the elastic members and the studs are miniaturized, and the force necessary to manipulate the horn switch assembly is reduced.
