A steering switch device has an operation member to be operated on a
steering wheel of a vehicle. An operation condition of the operation
member is controlled by a control unit when the steering wheel is
rotated. The operation member is for example a cylindrical member and
disposed operable in a rotation manner. When the steering switch is
rotated, a rotating operation of the cylindrical operation member is
restricted by the control unit. Alternatively, the rotating operation of
the operation member is controlled to be loaded. In a case that the
operation member is a button member for indicating a direction, a
pressing operation of the button member is controlled so as not to be
pressed or to be loaded by the control unit when the steering wheel is
rotated.
