METZGER 0912048 Switch, reverse light

Metzger 0912048 Switch – Reverse Light

The METZGER 0912048 Switch is a precision‑engineered component designed to control the activation of a vehicle’s reverse lighting system. It serves as the critical interface between the driver’s input and the illumination of the rearward-facing indicator lamps, ensuring safe maneuvering in low‑visibility conditions.

Key Functional Characteristics

• Dual‑pole construction: The switch incorporates two electrical contacts that simultaneously engage or disengage the reverse light circuit. This design guarantees reliable operation even under high vibration and temperature extremes typical of automotive environments.
• Integrated relay logic: When the gear selector is moved into reverse, the switch triggers a built‑in relay that powers the rear lamps. The relay’s contact closure is isolated from the driver’s direct control, providing an additional layer of safety and reducing electrical noise.
• Compact footprint: With dimensions tailored to fit within standard Ford dashboard panels, the switch occupies minimal space while maintaining robust mechanical strength.
• High‑temperature tolerance: Rated for automotive operating temperatures up to +125 °C, the component remains functional in hot climates and during prolonged engine operation.

Installation Context

The switch is specifically engineered for use in a range of Ford models, including but not limited to:

• Ford Focus (first and second generations)
• Ford C‑Max
• Ford Fiesta (including the Fiesta Max variant)
• Ford Fusion
• Ford Mondeo (IV generation)
• Ford Turnier

During installation, the switch is mounted within the driver’s control panel. It connects to the vehicle’s reverse gear selector via a dedicated cable harness that carries both power and signal lines. The harness interfaces with the car’s central electrical system through a connector that matches the OEM specification for the 0912048 part number.

Electrical Specifications

• Voltage range: 12 V DC (typical automotive battery voltage)
• Current rating: Up to 5 A per pole, sufficient for standard reverse lamp assemblies.
• Contact material: Silver‑plated brass to minimize corrosion and ensure low contact resistance.
• Operating temperature: –40 °C to +125 °C
• Mechanical life: Minimum of 50,000 cycles, guaranteeing long‑term durability in frequent gear changes.

Compatibility and OEM Alignment

The METZGER 0912048 Switch is an original equipment manufacturer (OEM) replacement part. It matches the exact electrical and mechanical specifications of the factory unit, ensuring seamless integration with the vehicle’s existing wiring architecture. Because it adheres to Ford’s stringent quality standards, users can expect performance that is indistinguishable from the original component.

Benefits for Vehicle Owners

• Enhanced safety: Reliable activation of reverse lights reduces the risk of accidents during parking or low‑speed maneuvers.
• Consistent performance: The switch’s robust construction prevents intermittent failures that could compromise visibility.
• Easy maintenance: Its standardized design allows for straightforward replacement without specialized tools.
• Long service life: Designed to withstand the rigors of daily driving, the component minimizes the need for frequent repairs.
