Wacker Neuson 5100026419 Oil Pressure Switch

The Wacker Neuson 5100026419 is a genuine OEM Oil Pressure Switch designed for DPU80, DPU90, and DPU110 series reversible vibratory plate compactors, as well as the HIF690. Sourced directly from Wacker Neuson, part 5100026419 is built to the exact specification of the original component — ensuring it integrates with your machine's engine monitoring system the same way the factory part does. This switch fits a broad range of Lec, Lem, rLec, and rLem variants across the DPU lineup, covering both standard and US-market configurations. If your compactor is showing low-oil warnings, running unprotected, or the existing switch has failed, this is the correct replacement to restore proper engine protection.

Key Features

• Correct Switching Threshold: — Calibrated to the precise pressure rating required by Wacker Neuson DPU-series engines, so the switch opens and closes at the right point — not too early, not too late.
• Genuine OEM Part: — Supplied by Wacker Neuson as original equipment, meaning this is the same part installed at the production line — not an adaptation or substitute.
• Broad DPU Series Coverage: — Fits DPU80, DPU90, and DPU110 reversible plate compactors across Lec, Lem, rLec, and rLem variants, including US-spec models and the HIF690.
• Direct-Connect Installation: — Matches the original thread pitch, body size, and connector interface, allowing straightforward removal and reinstallation without reworking the wiring harness or fittings.
• Engine Protection Restored: — A failed or inaccurate oil pressure switch leaves the engine running without low-oil shutoff protection, risking serious internal damage. Replacing it with 5100026419 restores that safeguard immediately.
• Critical Safety Function: — This switch is part of the engine's automatic shutoff circuit. A faulty switch can either allow the engine to run with dangerously low oil pressure or trigger nuisance shutdowns — both of which compromise safe, continuous operation on the jobsite.

The oil pressure switch monitors engine oil pressure and signals the control circuit when pressure drops below a safe operating threshold. In Wacker Neuson DPU reversible plate compactors, this triggers an automatic engine shutoff, protecting the motor from running dry and suffering bearing or cylinder damage. When the switch fails — whether it sticks open, sticks closed, or loses its calibration — the engine either loses its low-oil protection entirely or shuts down unexpectedly during operation, both of which point to an immediate need for replacement.
