The Bomag 05750564 Normally Closed Switch is a genuine OEM electrical switch designed for Bomag tandem rollers including the BW 120 AD, BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, and BW 154 AD-2. Sourced directly from Bomag, this switch matches the original component exactly, ensuring correct circuit behavior and a drop-in connection with no adjustments needed. When electrical reliability matters on your tandem roller, replacing a failed switch with the correct OEM part number 05750564 keeps control systems operating as designed.
Key Features
- OEM-Matched Electrical Specification — manufactured to Bomag's exact resistance, contact rating, and normally-closed circuit configuration, ensuring proper switching behavior in the machine's control system
- Direct Connector Compatibility — engineered to match the original mounting position and wiring harness connector on covered tandem roller models, allowing straightforward installation
- Broad Tandem Roller Coverage — fits the BW 120 AD, BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, and BW 154 AD-2 tandem rollers
- Consistent Circuit Integrity — a correctly functioning normally-closed switch maintains the default closed-circuit state the machine's electronics depend on; a faulty switch can trigger false fault codes or disable critical functions
- Electrical Safety Assurance — using the correct OEM switch prevents miswiring risks and ensures the control circuit responds predictably under all operating conditions
A normally closed switch is an electrical component that completes a circuit in its default, unpowered state and opens that circuit when activated. In compaction equipment, these switches are commonly used in safety interlocks, operator presence systems, and control circuits where a loss of signal must trigger a protective response. When a normally closed switch fails — sticking open or losing its contact rating — the machine may display fault codes, disable key functions, or behave unpredictably, making prompt replacement essential to safe and continuous operation.
