A switch device with an indicator, in which the indication resolution for the operation amount of a switch can be increased without increasing the number of light emitting elements of the indicator and with a low cost, is provided. The switch device includes an LED which emits light when the operation state of a knob of the switch corresponds to a first state and an LED which emits light when the operation state of a knob of the switch corresponds to a second state. When the operation state of the knob lies between the first and second states, at least one of the amount and color of light emission from the LEDs is changed in order to indicate an intermediate operation state of the switch.
