Abstract
A switch device includes a substantially disk-shaped operator; a substantially ring-shaped indicator provided between the operator and the light emitting elements disposed below the operator; and a visible portion formed in the center of an inner periphery of the operator. Since the indicator carrying indications of equipment functions in characters, symbols, figures or the like is formed separately from the operator, the indications will never turn sideways or upside down owing to the rotation of the operator.
