Technical Characteristics of the Stalk Assembly

The combination switch in this model is responsible for operating the turn signals and interacting with other control elements on the steering column. The integrated signal ribbon cable enables stable signal transmission between the steering wheel and the vehicle's electronic modules, which is crucial for the proper functioning of comfort and safety systems.

The design solution implemented by Mercedes ensures high operational repeatability, precise stalk positioning, and appropriate mounting rigidity on the steering column. This makes the driver's movements clearly registered, and the operation of the switches remains intuitive even under intensive use.

Function in the Vehicle Control System

This component belongs to the group of Switches, Control Elements, and Ignition Switches, responsible for the physical control of vehicle functions from the driver's level. The stalk assembly works with the electrical system and control modules, transmitting signals responsible for, among other things, turn signal indication and other functions assigned to the steering column.

A correctly selected combination switch directly impacts:

• clarity and repeatability of turn signal indication,
• stability of communication between the steering wheel and the vehicle's electronics,
• comfort of switch operation during daily driving.

Selection and Compatibility

The offered stalk assembly is an original Mercedes solution, which facilitates matching to a specific vehicle configuration. When selecting parts, it is advisable to pay attention to compatibility with the equipment version and the car's year of manufacture to maintain the full functionality of the steering column control system.

By using an original combination switch, you reduce the risk of electronic communication problems, errors in comfort system operation, and incorrect turn signal response. This is particularly important in premium vehicles, where the consistent operation of all components affects the overall driving experience.

Condition and Practical Application

The component is from a dismantled vehicle and is intended for users who want to restore the correct operation of the control system in their Mercedes without the need to invest in a new part. Choosing an original used combination switch allows for maintaining the factory characteristics of the stalk operation and compatibility with the vehicle's electrical system.
