Horn switch mechanism on steering wheel

摘要

A horn switch mechanism mounted on a steering wheel includes a stationary contact plate, movable contact plates disposed upwardly away from the stationary contact plate, and a horn pad covering over the contact plates. The stationary and movable contact plates are spaced away from each other by springs interposed between the stationary contact plate and the movable contact plates, while a distance of the space between the two contact plates is restricted by flanged spacers which are inserted downwardly through respective insertion bores of the movable contact plate and secured to the stationary contact plate. Each flanged spacer is received in a respective projection formed on the stationary contact plate. The stationary contact plate has its contact points formed on the upper ends of the guide projections, and the movable contact plate has its contact points formed on respective annular lower edges defining the insertion bores.
