Abstract
The knob switch device comprises a body, an operation knob mounted on the body, which is rotatable and movable along an axial direction of the knob, first and second switches operated by the rotation and the movement of the knob, respectively, an inclined projection having an inclined surface which is inclined relative to the knob, which is provided in one of body and the knob, and a sliding contact member provided in the other one of the body and the knob, which is slidingly moved along and in contact with the inclined surface when the operation knob is depressed. Since the sliding contact member is slidingly moved down along the inclined surface when the operation knob is depressed, the operation knob is rotated together with the axial movement by the depression, thus operating two switches.
