Key Functional Features

• Dual‑pole, single‑throw design: Provides a clean on/off signal to the reverse light circuit.
• Compact M12x1.5 mounting: Fits standard automotive harnesses and mounting brackets without modification.
• Robust insulation: Rated for temperatures up to +125 °C, ensuring longevity in engine bay environments.
• Low contact resistance: Guarantees efficient power delivery with minimal voltage drop.
• Sealed construction: Protects against moisture, dust, and vibration typical of automotive applications.

The switch is engineered to match the electrical specifications of numerous vehicle models. It is commonly found in:

• BMW series: E12, E23, E24, E30, E32, E36, E39, and newer generation models.
• Opel platforms: including the Manta, Monza, and various 1.8‑2.0 L engines.
• Saab vehicles: notably the 900 I and Z1 series.
• Other European manufacturers that use the same reverse light architecture.

Because of its standardized pinout and voltage handling, the Metzger 0912011 can also be adapted to modern vehicles with minor wiring adjustments.

1. Disconnect the battery before any electrical work to prevent shorts or accidental activation of the reverse lights.
2. Locate the existing reverse light switch or the harness that feeds the backup lighting system.
3. Remove the old component, noting the orientation and connector type.
4. Insert the Metzger 0912011 into the mounting bracket, aligning the M12x1.5 terminals with the harness pins.
5. Secure the switch using the supplied screws or retaining clips.
6. Reconnect the battery and test the reverse light function by engaging the gear selector to reverse; the lights should illuminate promptly.

The switch housing is fabricated from high‑strength polycarbonate, offering excellent impact resistance while keeping weight low. The internal contacts are plated with gold to resist corrosion and maintain conductivity over thousands of cycles.

• Designed for automotive life expectancy: typically 100,000+ operating hours.
• Passes rigorous vibration and shock testing in line with ISO 16750 standards.
• Sealed against ingress of water and dust (IP65 rating).

• Inspect the switch periodically for signs of wear or corrosion, especially if the vehicle operates in harsh climates.
• Avoid using abrasive cleaners on the contacts; a gentle wipe with isopropyl alcohol is sufficient.
• If the reverse lights fail to activate, check the wiring harness and fuse before replacing the switch.

The Metzger 0912011 Reverse Light Switch offers a dependable, OEM‑grade solution for controlling backup lighting across a broad spectrum of European vehicles.
