PROBLEM TO BE SOLVED: To provide a horn switch which is wide in an operation range, and furthermore is low in cost. SOLUTION: In the horn switch 10, connection is made by a stationary contact side connection part 100 for the copper foil 86 of a stationary contact 82 divided by a cavity part 94 corresponding to the vulnerable part of a pad part, and similarly, connection is made by a moving contact side connection part 102 for the copper foil 78 of a moving contact 74 divided by a cavity part 96. In this place, since the stationary contact side connection part 100 and the moving contact side connection part 102 are displaced along the cavity parts 94 and 96, when the horn switch 10 is turned on at the time of an air bag operation, the stationary contact side connection part 100 and the moving contact side connection part 102 are separately ruptured. For this reason, each of the connection part can be quickly ruptured at low loading as compared with that of the case that the stationary contact side connection part 100 is piled up to the moving contact side connection part 102. |
