Product Overview

The Febi Bilstein 18308 Switch for Power Window Regulator is a high‑performance, OEM‑grade component designed specifically for the front right power window system of select Mercedes‑Benz models. This switch serves as the electrical interface that controls the motorized lift and lower functions of the vehicle’s window regulator.

Design & Build Quality

The switch features a robust polycarbonate housing that resists impact, heat, and moisture—critical for long‑term reliability in automotive environments. Its internal contacts are constructed from gold‑plated brass, ensuring low resistance and excellent conductivity even after repeated use. The button mechanism is engineered to provide a crisp tactile response, giving the driver clear feedback when operating the window.

Key Design Features

• Compact Footprint: Fits seamlessly into the existing dashboard architecture without requiring additional space or modifications.
• Durable Seal: Integrated gasket prevents dust and water ingress, extending component life.
• Heat‑Resistant Materials: Maintains structural integrity up to 120 °C, protecting against engine bay heat.

Compatibility & Fitment

The switch is engineered for the following Mercedes‑Benz platforms:

• W124 (Class E) – Front Right Power Window Regulator
• 190 (W201) – Front Right Power Window Regulator, 1982–1993 models
• Other related G‑Class and S‑Class variants that share the same regulator architecture.

It is a direct replacement for the original OEM part, ensuring full compatibility with the vehicle’s electrical system, safety features, and window control logic.
