Abstract
A horn switch device includes a retractable body, an unmoving body, first and second biasing members for biasing the retractable body in a restoring direction, and first and second contact members. The contact members are attached to, and move with, the retractable body, and are capable of contacting each other by movement of the retractable body. The first biasing member pushes the first contact member and the second contact member apart. The second biasing member pushes the second contact member toward the first contact member. When a module cover is depressed, the biasing members are compressed to bring the contact members into contact with each other, thereby sounding the horn. Since the biasing members are arranged in series, vehicle vibration can be absorbed, thereby preventing accidental contact of the contact members. The device facilitates positioning of the contact members, thereby simplifying assembly of a steering wheel and an airbag system.
