A plate for mounting an airbag, and for carrying horn switch contacts is snapped to the hub of a steering wheel. The plate may move between actuated and non-actuated positions relative to the hub. Integral springs bias the plate to a non-actuated position. An operator may apply a force to the steering wheel central portion to overcome the spring force and move the plate to an actuated position at which a horn switch is actuated. The plate has slots which snap on snap fingers from the hub. The snap on assembly simplifies and improves the overall assembly of the steering wheel. Moreover, the use of the integral springs also simplifies and improves the overall assembly. The airbag cover is preferably guided in a central area on the steering wheel to insure that the airbag cover is centered, thus minimizing gaps between the airbag cover and the steering wheel.
