The Bomag 05728386 Regulator Switch is a genuine OEM component designed for BPR-series reversible vibratory plates and BW 71 walk-behind rollers. As a direct OEM replacement, this regulator switch is built to the same specification as the original, ensuring correct electrical response and reliable control operation across every compatible machine. This switch fits the BPR 30/38 D-2, BPR 30/38 D-3, BPR 40/45 D, BPR 40/45 D-2, BPR 40/45 D-3, and BPR30 /38 reversible vibratory plates, as well as the BW 71 E-2 and BW 71 EHB-2 walk-behind rollers — making part number 05728386 a versatile stock item for operators running mixed fleets of these compact Bomag machines.
Key Features
- OEM Electrical Specification — sourced directly from Bomag, this switch matches the original resistance and switching characteristics required for correct regulator function on your machine
- Drop-In Replacement — engineered to the same connector and mounting configuration as the factory original, so this regulator switch installs directly without modification
- Broad Fitment Coverage — fits BPR 30/38 and BPR 40/45 reversible vibratory plates across multiple generation suffixes, plus BW 71 E-2 and BW 71 EHB-2 walk-behind rollers
- Consistent Regulator Control — a functioning regulator switch maintains accurate operator control over machine output; a failed or worn switch can cause erratic regulation, loss of control response, or failure to start
- Electrical Safety Assurance — as a genuine OEM switch, part number 05728386 meets Bomag's original circuit and safety design requirements, reducing the risk of electrical faults in the control system
The regulator switch is an electrical control component that governs the output or behavior of the machine's regulator circuit — typically managing engine throttle, vibration frequency, or charging system regulation depending on its position in the control system. When this switch is operating correctly, the operator maintains precise, predictable control over machine function. A worn, corroded, or failed regulator switch can produce inconsistent machine response, warning indicators, or a machine that fails to run at the correct operating parameters. Replacing a faulty switch with a genuine OEM part restores the original control characteristics and keeps the machine performing as intended.
