Operating part for control functions in vehicle has light conducting body with latching protrusions, recesses on outer edge axial surfaces that interact with latching hooks on clamp spring

摘要

The operating part has several rotary knobs whose position is indicated by a light indicator containing a LED and optical conductor. One knob (2) has a light conducting body (4) interacting directly with the LED and with a light output surface that interacts with the input surface of a light conducting plate (7) leading to the other rotary knobs. The light conducting body has latching protrusions and recesses on the axial surfaces of its outer edge that interact with latching hooks on a clamp spring pushed between mounting ribs on the light conducting plate and held between a plate edge and a housing rib.
