Abstract
A switch device is provided which allows easy recognition of the operation amount of the switch device with an inexpensive structure and without the need for an operator to change the posture or the like, even when a blind spot region is generated in an indicator as a special indication region at the time of indicating the operation amount of the switch. When the special indication region on the indicator cannot be seen directly because it is blocked by a knob, the state of the indicator in the special indication region is expressed using a visible region on the indicator which is always visible. Thus, the operator can recognize the operation amount of the switch device in the blind spot region without changing the posture or the like and using a simple structure of the switch device.
