The Bomag 05821071 Maintenance Switch is a genuine OEM component designed for a wide range of Bomag single drum rollers, tandem rollers, and refuse/landfill compactors. Sourced directly from Bomag, this switch matches the original part in form, fit, and electrical specification — so there is no guesswork when it comes to compatibility. This maintenance switch is confirmed to fit models including the BW 213 D, BW 213 D-3, BW 177 D-3, BW 212 D-3, BW 216 D-3 and BW 178 D-3 single drum rollers, the BW 120 AD, BW 164 AD, BW 174 AD, BW 180 AD, BW 184 AD and BW 202 AD-2 tandem rollers, as well as BC 670 RB and BC 570 RB refuse/landfill compactors, among many other covered machines.
Key Features
- Correct Electrical Specification — built to OEM electrical tolerances, ensuring the switch operates at the correct activation threshold and integrates cleanly with Bomag's onboard maintenance-interval circuitry.
- Drop-In OEM Replacement — this switch matches the original connector, mounting configuration, and switching logic of the factory-installed unit, allowing straightforward installation without reworking wiring or brackets.
- Broad Fitment Across Bomag Roller Families — fits an extensive lineup of BW-series single drum rollers including the BW 177 D-3, BW 213 DH-3, and BW 213 PDH-3; tandem rollers including the BW 161 AD-2, BW 170 AD, BW 174 AC, BW 202 AHD-2, and others; plus BC 670 RB and BC 570 RB refuse/landfill compactors.
- Uninterrupted Maintenance Monitoring — a functioning maintenance switch keeps the machine's service-interval tracking accurate; a failed or missing switch can mask overdue service alerts, leading to missed inspections and accelerated component wear.
- Electrical System Integrity — as part of the machine's control and alerting system, an out-of-spec switch can cause false readings or failure to trigger required maintenance prompts — using the correct OEM part protects the accuracy of the entire monitoring system.
The maintenance switch monitors operating hours or service conditions and signals the machine's control system when a scheduled maintenance interval has been reached. It plays a key role in keeping service cycles on track by triggering dashboard indicators or system prompts that alert the operator or technician to perform required maintenance. When this switch fails or degrades, the monitoring signal can be lost entirely — causing the machine to run past service intervals without warning, which puts other drivetrain and hydraulic components at greater risk of premature wear.
