Bomag 05750840 Interval Switch

The Bomag 05750840 Interval Switch is a genuine OEM component designed for a wide range of Bomag BW-series rollers, including tandem rollers, walk-behind rollers, and pneumatic tyred rollers such as the BW 120 AD, BW 213 D, BW 75 ADL, BW 164 AD-2, BW 202 AD-2, and BW 24 R, among others. Sourced directly from Bomag, this interval switch matches the original specification for a drop-in replacement with no guesswork on compatibility. Confirmed fitment extends across the BW 80, BW 90, BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, BW 138, BW 141, BW 144, BW 151, BW 154, BW 161, BW 164, and BW 202 tandem roller families, as well as walk-behind models including the BW 900-50, and pneumatic tyred rollers including the BW 24 R and C 560 B. Using the correct OEM part ensures the switch operates within its intended electrical parameters, protecting downstream components and keeping spray or warning intervals timed precisely as engineered.

Key Features

• OEM Electrical Accuracy — manufactured to Bomag's original resistance and timing specifications, ensuring the switch cycles at the correct intervals rather than approximating them
• Direct-Fit Replacement — matches the original connector, mounting footprint, and wiring interface for a straightforward swap on all covered models
• Broad BW-Series Coverage — confirmed fit across Bomag tandem rollers including the BW 100 AD-3, BW 131 AD-3, BW 164 AD-2, and BW 202 AD-2, plus walk-behind rollers and pneumatic tyred rollers such as the BW 24 R and C 560 B
• Consistent Interval Timing — a properly functioning interval switch keeps spray systems or timed functions operating on schedule; a faulty switch leads to erratic cycling, missed applications, or continuous operation that wastes resources
• Genuine Bomag OEM Part — part number 05750840 is sourced through authorized Bomag supply channels, so you receive the same component installed at the factory

The interval switch controls the timed cycling of an electrical circuit on the roller — most commonly governing the water spray system that prevents asphalt or material from sticking to the drums during compaction passes. It opens and closes the circuit at set intervals, delivering bursts of water or activating a function at the correct frequency. When the switch fails or drifts out of spec, the spray may run continuously, stop working entirely, or cycle at the wrong rate, affecting compaction quality and increasing water or fluid consumption.
