Wacker Neuson 5100056844 Oil Switch Assembly

The Wacker Neuson Oil Switch Assembly is a genuine OEM component designed for BPS, WP, and PDT series vibratory plates and rammers, including the BPS1030A, BPS1135A, BPS1340A, WP1550A, PDT2A, PDT3A, and PDI3A. As a direct OEM part, it is built to the exact tolerances and switching specifications of the original, ensuring consistent operation and a clean drop-in installation. This assembly covers a broad range of US and EU configured models across the BPS and WP lines, making it the correct choice whether you are servicing North American or European market machines. Sourcing the directly through Wacker Neuson's authorized parts network gives you confidence that the part matches your machine's original electrical and mechanical specifications.

Key Features

• OEM Switching Accuracy — Manufactured to the original circuit activation thresholds, so the switch trips at the correct oil pressure level every time.
• Direct Drop-In Installation — Matches the original connector and thread specification of the OEM assembly for a straightforward swap with no adaptation needed.
• Broad Model Coverage — Fits BPS1030A, BPS1135A, and BPS1340A vibratory plate series (US and EU configurations), plus WP1550A, PDT2A, PDT3A, and PDI3A models.
• Protects Engine Integrity — A correctly functioning oil switch will cut power before low oil conditions cause internal engine damage; a faulty one leaves your engine unprotected.
• Electrical Safety Compliance — As a genuine OEM electrical assembly, it meets the original design requirements for safe circuit interruption, critical on equipment where an undetected oil fault can escalate quickly.

The oil switch assembly monitors engine oil pressure and triggers an automatic shutdown if pressure drops below a safe operating threshold. This protects the engine from running in a low-oil condition that would otherwise cause rapid wear or seizure of internal components. When the switch fails — whether it trips erroneously or stops responding altogether — the machine may shut down unexpectedly during operation or, more dangerously, continue running without the protection it relies on.
