A lighting control operating unit generating digital adjusting commands which are transmitted to a processing unit via a data link includes several control elements, including key buttons, slide controls and/or rotary controls, which are disposed at the upper side of a housing. At least one dual encoder is provided in a control panel of the lighting control operating unit allowing users to enter input values. The dual encoder presents a first shaft rotatably mounted in a housing, and a second shaft mounted in the housing so as to be coaxially rotatable, and corresponding first and second rotation signal generators Both shafts include actuating elements transmitting adjusting movements. The actuating elements are a rotary disk and/or a rotary swivel configured to be coaxially turned in opposite directions.

A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.
