The Bomag 05834120 Float Switch is a genuine OEM component designed for a wide range of Bomag tandem rollers and cold milling machines, including BW 154, BW 161, BW 174, BW 190, BW 191, BW 202, BW 203, BW 205, and BW 206 series tandem rollers, as well as BM 500/15 and BM 600/15 cold milling machines. Sourced directly from Bomag, this float switch matches the original part exactly, ensuring a drop-in installation with no guesswork. The correct float switch is critical to fluid level monitoring and machine protection — keeping your equipment running within safe operating parameters.
Key Features
- Genuine OEM Sensing Accuracy — manufactured to Bomag's original switching threshold and float travel specifications, so fluid level detection is accurate and consistent across operating conditions
- Direct-Fit Replacement — matches the original connector, thread pitch, and housing dimensions for straightforward installation on compatible Bomag tandem rollers and cold milling machines
- Broad Model Coverage — fits a wide range of Bomag tandem rollers including BW 141 AD-5, BW 154 AP-4, BW 161 AD-4, BW 174 AP-4i, BW 202 AD-5, BW 206 AD-5, and more, plus BM 500/15 and BM 600/15 cold milling machines
- Machine Protection Built In — a properly functioning float switch triggers low-fluid alerts before damage occurs; a failed or stuck switch can mask dangerously low fluid levels and lead to costly component failure
- Electrical Integrity — OEM-matched switching resistance and float buoyancy rating prevent false readings, nuisance shutdowns, or missed warnings that an aftermarket substitute might introduce
A float switch monitors the fluid level inside a reservoir — typically a hydraulic tank, water tank, or coolant system — and sends an electrical signal to the machine's control system when the level drops below a safe threshold. When the float drops with falling fluid, it opens or closes a circuit to trigger a warning light or automatic shutdown, protecting the machine from operating in a low-fluid condition. A worn or failed float switch can stick in position, causing either constant false alarms or, more dangerously, no warning at all when fluid is critically low.
