A switch device includes an operation knob rotatably supported by a case, and switch mechanisms which can convert a switch circuit (not shown) disposed inside the case by performing a rocking operation on the operation knob. A cam member having a cam face which can deliver click feelings to the operation knob is disposed in the case. The switch circuit is converted in conjunction with the rocking operation of the operation knob, and click feelings are created so as to be delivered to the operation knob.
