Bomag 05579431 Rotary Button

The Bomag 05579431 Rotary Button is a genuine OEM component designed for a wide range of Bomag BW-series tandem rollers, single drum rollers, and pneumatic tyred rollers. Sourced directly from Bomag, this rotary button matches the original part in form and function, ensuring a correct, confident installation every time. Compatible machines include BW 141 AD-5, BW 151 AD-5, BW 161 AD-5, BW 202 AD-5, BW 213 D-5, BW 226-5, BW 28 RH, and many more BW-series models in the -5 and -50 generation lines. Keeping this small but critical control component in proper working order helps maintain accurate, responsive machine operation on the job.

Key Features

• Genuine Bomag OEM Construction — manufactured to the same material and dimensional specifications as the original, so the rotary button seats, rotates, and engages exactly as intended from the factory floor
• Direct-Fit Replacement — engineered as a drop-in swap for the original component, with the correct profile and attachment geometry to fit the control panel interface on covered BW-series machines
• Broad BW-Series Coverage — fits an extensive range of Bomag BW tandem rollers (including BW 141 AD-5, BW 161 AC-5, BW 202 AD-50, and BW 206 AD-5), single drum rollers (including BW 145 D-5, BW 177 DH-5, BW 213 D-5, and BW 226 DH-5), and pneumatic tyred rollers (including BW 11 RH-5 and BW 28 RH)
• Positive Operator Control — a worn or damaged rotary button can produce inconsistent detent feel or unintended control input; replacing it restores crisp, repeatable selector action for the operator
• Verified Part Number Traceability — order with confidence using Bomag part number 05579431, the exact OEM reference for this component across all listed machine configurations

A rotary button is a control panel selector component that the operator turns to engage or switch between machine functions — such as drive mode, vibration settings, or auxiliary controls, depending on the specific application. It works in conjunction with the underlying switch or valve body, transmitting the operator's input through a precise rotational movement. When the button becomes cracked, loose, or worn smooth, it can slip during operation, making it difficult to select or hold the intended setting reliably — which disrupts workflow and can mask the true position of a control.
