Metzger 0911041 Brake Light Switch

Overview

The Metzger 0911041 Brake Light Switch is a high‑performance component engineered to provide reliable activation of vehicle brake lights and related safety systems. Designed with precision, this switch ensures that every time the driver depresses the pedal, the brake lights illuminate instantly, enhancing visibility for following traffic.

Design and Build Quality

The switch features a robust housing constructed from high‑strength polymer, resistant to vibration, temperature extremes, and chemical exposure. Its compact footprint allows seamless integration into existing pedal assemblies without requiring extensive modifications. The internal contacts are made of gold‑plated alloy, guaranteeing low resistance and long‑term conductivity even under repeated cycling.

Multilingual Identification

Across global markets, the component is referenced by several names that reflect local language conventions:

• Metzger 911041 Bremslichtschalter (German)
• Interruttore Luce Freno (Italian)
• Interruptor de luces freno (Spanish)
• Contacteur de feux stop (French)
• Przełącznik świateł hamowania (Polish)
• Interrupteur des feux de freins (French, alternate spelling)
• Interruptor de luz de stop (Spanish, alternate spelling)
• Kontakt til bremselys (Danish)

These designations all refer to the same 0911041 model, ensuring that users worldwide can identify and source the correct part for their vehicle.

Compatibility with BMW Models

The switch is specifically engineered for a wide range of BMW vehicles, including:

• E30, E36, E12, E38, E34, E23, E32, Z1, E28, 61318360420
• 3 Series (E30), 5 Series (E36), 6 Series (E34), and 7 Series (E38)
• Older models such as the Z1 and newer E32 variants

Its standardized mounting interface allows direct replacement of OEM switches without the need for custom adapters.

Installation Procedure

1. Disconnect the vehicle’s battery to eliminate electrical hazards during installation.
2. Remove the existing brake light switch by loosening the mounting screws and gently pulling it from the pedal assembly.
3. Align the 0911041 with the mounting holes, ensuring that the contact pins line up precisely with the pedal’s cam mechanism.
4. Screw the new switch into place, tightening to the manufacturer’s torque specifications.
5. Reconnect the battery and test the brake lights by pressing the pedal; illumination should occur immediately.

Operational Characteristics

The switch operates on a simple mechanical principle: when the brake pedal is depressed, a cam engages the internal contacts, completing the circuit that powers the brake lights. Key performance attributes include:

• Fast response time – milliseconds between pedal depression and light activation.
• Low electrical resistance – ensuring minimal voltage drop across the circuit.
• High cycle life – rated for over 200,000 actuation cycles without degradation.

Maintenance Guidelines

Routine inspection is recommended to ensure optimal performance:

• Check for physical damage such as cracks or wear on the housing.
• Verify that the internal contacts remain clean; use a contact cleaner if corrosion is observed.
• Ensure that the mounting screws are tight and free from rust.
• Replace the switch immediately if any irregularities in brake light operation are detected.

Technical Specifications

Conclusion

The Metzger 0911041 Brake Light Switch exemplifies engineering excellence tailored for BMW vehicles. Its durable construction, precise operation, and broad compatibility make it an indispensable component for maintaining vehicle safety standards. Whether you are a professional technician or an enthusiast seeking to preserve the integrity of your classic BMW, this switch delivers dependable performance that drivers can trust on every journey.
