The design is intended for installation in the Vito W639 steering wheel, maintaining the original button layout and operating logic. Thanks to its factory origin, the correct mounting points and compatibility with the electrical harness are preserved.

Benefits of using original switches

Why choose original used Mercedes parts

Original used sub-assemblies, such as multifunction steering wheel switches, often prove to be more predictable in operation than replacements of unknown origin.
