The offered switch has been specifically designed for selected Audi higher-class models, such as A6, A7 4G8, and A8, maintaining the factory manufacturing standard. The housing and connector design are prepared for installation in the original location, which simplifies installation and reduces the need for modifications to the upholstery or wiring harness.

The element features a dedicated electrical connector, adapted to work with the vehicle's installation, so that after correct connection, the button can operate in plug-and-play mode, without additional software adaptations.
