Illuminated push button for motor vehicle - has reciprocal, different shapes of controllable resistors and switches, and illuminated part to display their function

摘要

The push-button includes an inner light source to illuminate the button and display its function. A first operating element (1) is fixed to an inner rigid shaft (2a), and has an outer element to display the function type. A light refracting part (16) refracts the light generated from the inner light source. A light conducting part (1a) transmits the radiated light to illuminate the outer element. A second operating element (3) is fixed to a rotatable outer shaft (2b) arranged around the inner fixed shape. The second operating element has a transparent part (3a) for the transmission of the radiated light. ADVANTAGE - Improved operability, displaying on illuminated part function of controllable resistors and switches so that it can be clearly recognised.
