Horn switch device, airbag system, and steering wheel

摘要

To provide a horn switch device in which the contacts can easily be positioned to each other, so that the assembly to an airbag system is easy. A first contact member (61) is provided via an insulating pedestal (53) to an overhang (45) fixed to a module cover (40). A second contact member (62) extends from a ring (63) that is disposed around a guide shaft (50). The second contact member (62) passes through the window (56) of a contacting body (55) to extend to the position below the first contact member (61). When the module cover (40) is depressed, the second contact member (62) comes into contact with the lower rim of the window (56), being stopped from further falling. The contact members (61 and 62) thus come into contact with each other to sound the horn.
