The Wacker Neuson 5100056844 Oil Switch Complete is a genuine OEM component designed for BPS1030A, BPS1135A, and BPS1340A series vibratory plate compactors. As a direct OEM replacement, this switch is manufactured to the same specification as the original, ensuring proper oil pressure monitoring across all covered BPS plate compactor variants — including US and EU configurations, as well as the Aws and Aws variant models. Fitment spans the full BPS1030A, BPS1135A, and BPS1340A model families, making the 5100056844 the correct choice whether you're servicing a standard or wide-plate configuration. Sourcing a genuine Wacker Neuson part means no guesswork on compatibility or sensor calibration — the switch is ready to install as-designed.
Key Features
- Genuine OEM Sensor Accuracy — Built to Wacker Neuson's original pressure threshold specification, so the switch triggers at the correct oil pressure level — not an approximated range.
- Direct Drop-In Replacement — Matches the original connector, thread pitch, and housing of the factory switch for a straightforward swap during routine service or repair.
- Broad BPS Series Compatibility — Confirmed fitment across BPS1030A, BPS1135A, and BPS1340A models in both US and EU configurations, including standard A, wide Aw, and Aws variants.
- Engine Protection Restored — A functioning oil switch is your machine's first line of defense against low-oil engine damage; replacing a faulty unit restores that critical protection layer.
- Fuel System Safety Relevance — An inaccurate or failed oil switch can allow the engine to run under dangerously low oil pressure, risking seizure; a genuine replacement ensures the shutoff circuit operates as engineered.
The oil switch — also known as an oil pressure switch — monitors engine oil pressure during operation and signals the machine's control circuit when pressure drops below a safe threshold. On BPS plate compactors, this switch acts as a safeguard: if oil pressure falls dangerously low, the switch triggers an alert or shuts the engine down to prevent internal damage. When the switch fails or gives a false reading, the machine may shut off unexpectedly during normal use, or — more critically — continue running with insufficient oil pressure and suffer engine damage. Replacing a worn or faulty switch with the correct OEM unit restores the accuracy of this protective function.
