This part is confirmed to fit the BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers, making it a straightforward drop-in replacement for operators keeping their machines in top working order.
Key Features
- Genuine OEM Electrical Spec — manufactured to Bomag's original switching characteristics, including correct contact ratings and actuation behavior for this tandem roller application
- Direct-Fit Replacement — engineered to the same mounting configuration and connector interface as the original, so this switch installs cleanly into the existing position
- Broad Tandem Roller Coverage — fits the BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers across Bomag's -2 generation lineup
- Correct Circuit Function Restored — a faulty switch can cause erratic or non-responsive controls; replacing it with an OEM-matched unit restores predictable, dependable circuit operation
- Operational Safety — switches in roller control circuits are critical to operator command response; using a part built to the original specification helps ensure control inputs perform as intended
A switch in this application serves as the electrical interface between the operator's input and a downstream system — whether that's engaging a drive function, activating a circuit, or triggering a safety interlock on the roller. When a switch wears, corrodes, or fails internally, the connected system may become unresponsive, intermittent, or behave unpredictably, making diagnosis difficult and normal operation unreliable. Replacing a failed switch with an OEM unit, such as part number 64003478, ensures the correct electrical characteristics are restored so the machine responds as its design intended.
