A controller device having a rotary-push-button switch is arranged on a frame and the rotary-push-button switch is movable with respect to the frame between at least a first operating position and a second operating position. A position detecting element is used to determine whether the rotary-push-button switch is in the first or second positions. When the position detecting element indicates that the switch is in the first position, the rotary-push-button switch is operated in a first mode. Similarly, the rotary-push-button switch is operated in a second mode when the position detecting element indicates that the switch is in the second position.
