Slider control
摘要:
At a slot in a control panel of an automotive vehicle, the slot traversed by a slidable actuating lever for controlling the operating state of a heating and ventilating or air conditioning system of an automotive vehicle, an elongate web is disposed parallel and proximate to the slot for preventing the passage of light and dust. The web covers the slot, is attached at its ends to a control panel plate and traverses an opening in the lever.
