Abstract
A steering wheel (12) incorporates an air bag unit (22). The air bag unit has a cover door (30) with a transducer (38) molded in a deformable front wall (35) of the cover door. The transducer is operably connected to an electrical circuit (42) that actuates a horn (44) when the circuit senses an actuating output voltage at the output lead (41) of the transducer (38). The transducer produces the actuating output voltage when hand pressure is exerted on the front wall (35).
