Key Functional Features

• Mechanical Activation: The switch operates through a simple lever mechanism that engages when the brake pedal is depressed. This design eliminates the need for complex electronic sensors, ensuring reliable operation even in harsh environments.
• Low Current Draw: With a typical operating current of 0.5 A, the switch consumes minimal power, reducing stress on the vehicle’s electrical system and extending battery life.
• High Contact Resistance Tolerance: The internal contacts are engineered to maintain low resistance under repeated cycling, guaranteeing consistent brake light illumination without flicker or delay.
• Wide Temperature Range: Rated for operation from –40 °C to +85 °C, the switch remains functional in extreme climates, making it suitable for both European and tropical markets.

Design & Construction

The METZGER 0911122 Switch features a compact housing made of high‑strength polymer that resists abrasion and chemical exposure. The lever arm is constructed from anodized aluminum, providing durability while keeping the overall weight low. The switch’s internal contacts are plated with gold to prevent corrosion and maintain conductivity over thousands of cycles.

Vehicle Compatibility

This model was engineered to fit a broad spectrum of vehicles, including but not limited to:

• Citroën, Peugeot, Opel, Fiat, Suzuki, Toyota (various models such as the RAV4, Land Cruiser Prado, Yaris, and Swift)
• Honda, Hyundai, Kia, Mazda, Nissan, Subaru, Volkswagen, and many others
• Both front‑wheel drive and all‑wheel drive configurations

The switch’s standardized mounting dimensions allow for straightforward installation in most brake light assemblies without the need for custom adapters.

Installation Guide

1. Disconnect Power: Ensure the vehicle battery is disconnected to prevent accidental short circuits during replacement.
2. Remove Old Switch: Unscrew or unclip the existing brake light switch from its mounting bracket. Carefully note the orientation of the wiring harness for correct reassembly.
3. Mount New Switch: Position the METZGER 0911122 in the same location, aligning the lever arm with the brake pedal mechanism. Secure it using the original fasteners or equivalent hardware.
4. Reconnect Wiring: Attach the vehicle’s brake light wiring harness to the switch terminals, ensuring a snug fit and correct polarity.
5. Test Functionality: Reconnect the battery and activate the brake pedal. The brake lights should illuminate immediately with no delay or flicker.

Maintenance Tips

• Inspect the lever arm for wear after every 10,000 miles; replace if any play is detected.
• Clean contact surfaces with a non‑abrasive electrical contact cleaner to remove dust or corrosion.
• Avoid exposing the switch to excessive moisture; use a protective sealant if operating in wet climates.
