Product Name: Grammer 90.6 Truck Sensors – New Condition Adjustment Knob Backrest Seat Switch Parts (OE:1161982 2106080)

The Grammer 90.6 Adjustment Knob, a key backrest seat switch part in new condition, works in tandem with truck sensors to deliver precise control over seat backrest positioning, serving as a critical interface for driver comfort in commercial vehicles. Bearing OE numbers 1161982 and 2106080, this component is engineered to Grammer’s exacting standards, ensuring seamless compatibility with their seat systems and sensor integrations, making it an essential replacement for maintaining intuitive and reliable backrest adjustments.

As a core part of the seat’s control mechanism, the adjustment knob functions as both a switch and a regulator: when turned or pressed, it communicates with truck sensors to trigger backrest movement—whether reclining, tilting, or locking into position—allowing drivers to customize angles for optimal spinal alignment during long hauls. The sensor integration ensures precision, with incremental adjustments that respond smoothly to input, avoiding abrupt movements that could disrupt comfort or focus. This synergy between knob and sensors eliminates common issues with worn parts, such as unresponsive controls, inconsistent positioning, or sensor misalignment that leads to inaccurate backrest angles.

Crafted as a new-condition part, it arrives free from wear, corrosion, or internal damage, with a pristine finish and flawless functionality. The knob’s housing is typically made from high-impact plastic or reinforced polymer, chosen for its durability against frequent use, temperature fluctuations, and vibration in truck cabs. Its ergonomic design features a textured grip for easy operation, even with gloved hands, while internal contacts (for switch functionality) are made from conductive materials to ensure reliable electrical communication with sensors, preventing signal loss or intermittent performance.

Designed as an OE-grade component (1161982 2106080), it fits perfectly into Grammer’s seat assemblies, aligning with existing sensor wiring and mounting points. Installation is straightforward, requiring no modifications to the seat frame or sensor systems—simply replacing the old knob with this new part restores full control functionality, minimizing downtime for maintenance.

For drivers, this adjustment knob enhances daily comfort by enabling quick, precise backrest tuning, reducing muscle strain and promoting better posture during extended shifts. For fleet managers, its new-condition reliability ensures consistent performance, reducing the need for repeated repairs and extending the service life of seat control systems.

With OE numbers 1161982 and 2106080, the Grammer 90.6 Adjustment Knob is more than a switch part—it’s a bridge between driver input and sensor-driven precision. By combining ergonomic design, durable construction, and seamless sensor integration, it ensures every backrest adjustment is smooth, accurate, and tailored to the driver, mile after mile.
