The Bomag 05755027 Ignition Switch is a genuine OEM component designed for Bomag BW 60 S, BW 65 HS, BW 65 S, BW 75 S, and BW 90 S walk-behind light rollers. As a direct OEM replacement, this ignition switch meets Bomag's original design and electrical specifications, ensuring the switch integrates correctly into the machine's starting and shutoff circuit without adaptation. If your roller is failing to start, cycling power intermittently, or won't shut off cleanly, a worn or failed ignition switch is a common cause — and replacing it with part number 05755027 restores normal operation fast.
Key Features
- OEM Electrical Accuracy — Matches the original switching contacts, terminal configuration, and key-cylinder interface specified by Bomag, so the starting and shutdown circuit performs exactly as designed.
- Drop-In Replacement — Engineered to the same mounting dimensions and wiring connector layout as the factory unit, allowing straightforward installation on compatible walk-behind light rollers.
- Broad Walk-Behind Roller Coverage — Fits the BW 60 S, BW 65 HS, BW 65 S, BW 75 S, and BW 90 S walk-behind light rollers, covering multiple machines in Bomag's compact roller lineup.
- Restored Start/Stop Reliability — A correctly functioning ignition switch gives operators crisp, repeatable control over engine start and shutdown — protecting both the machine and the operator from unpredictable electrical behavior.
- Genuine OEM Sourcing — Supplied as an authentic Bomag part, backed by OEM traceability and manufactured to the tolerances required for a safety-critical electrical control component.
The ignition switch is the primary electrical control that connects and disconnects power between the battery and the engine's starting and ignition systems. On Bomag walk-behind light rollers, it governs both the engine start sequence and the safe shutdown of the machine — making it a critical operator-interface component. When the switch wears out or fails internally, symptoms typically include a roller that won't crank, intermittent starting, or an engine that cannot be shut off via the key, all of which take the machine out of service until the switch is replaced.
