Key Features

• Genuine OEM Control Accuracy — manufactured to Bomag's original specification, ensuring the rotary button delivers the correct detent feel, rotation range, and electrical or mechanical response for the specific control circuit it serves
• Direct Drop-In Replacement — matches the original mounting footprint and interface exactly, so this rotary button installs into the control panel without any modification or rework
• Broad BW-Series Coverage — fits Bomag BW-series tandem rollers including the BW 141 AD-5, BW 151 AD-5, BW 161 AD-5, BW 202 AD-5, and BW 206 AD-5; single drum rollers including the BW 145 D-5, BW 177 D-5, BW 211 D-5, BW 213 D-5, BW 216 D-5, BW 219 D-5, and BW 226-5; and pneumatic tyred rollers including the BW 11 RH-5 and BW 28 RH
• Restored Operator Control — a worn or damaged rotary button can cause erratic, unresponsive, or stuck control inputs; replacing it with part number 05579491 restores smooth, precise operator command over the affected machine function
• Operator Safety Assurance — control interface components directly affect an operator's ability to command machine functions predictably; using a genuine OEM rotary button ensures the control responds as designed, reducing the risk of unintended machine behavior

A rotary button is an operator-interface control component mounted on the machine's control panel, used to select or adjust a specific machine function — such as vibration mode, compaction settings, or drive parameters — by rotating to a set position. It acts as the direct link between the operator's input and the machine's control system, so a crisp, reliable action is essential for accurate and repeatable operation. When a rotary button becomes worn, cracked, or internally damaged, it can produce intermittent signals, fail to hold a selected position, or become unresponsive altogether, compromising the operator's ability to control the roller correctly.
