Steering wheel rim horn blow mechanism
 A vehicle steering wheel includes an annular metal core with a molded plastic body and may include an outer molded layer of vinyl, wrap of leather or the like. A recess is provided extending along the inside rim of the wheel. An elastomeric cover, such as urethane rubber, covers the switch. Annular voids in the elastomeric cover may be selectively placed to provide the desired resilient characteristic. The strip switch preferably includes two outer strips and one inner strip of thin, flexible plastic. Electrically conductive, silver ink coatings are provided on the two outer strips facing each other to form strip contacts and having leads connected to the horn circuit. An inner strip or ribbon forms an insulator with openings to allow engagement of the two conductor strips under tactile pressure at any point around the rim. The inner ribbon is coated on both sides with adhesive to hold the strips together in an integral unit. The strips have sufficient memory to separate when pressure is released to open the contacts, and in this regard Mylar or other suitable plastic material is preferred. In an alternative embodiment, two resilient outer strips are also provided. One of the two strips carries a pair of separate strand conductors operable when jump connected to complete the circuit. The other strip has a conductive coating and spans the conductors, and under applied pressure jump connects the conductors through elongated openings in the insulator ribbon.
