The Wacker Neuson is a genuine OEM Oil Pressure Switch designed for a range of Wacker Neuson equipment including HSH350 hydronic surface heaters, E1100 ground heaters, RD15 tandem rollers, and DPU reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this part is manufactured to the same specification as the original component it replaces. Confirmed fitment spans the HSH350, E1100, RD15, DPU 3050HE, DPU 3060HE-TS, DPU 3750Hets, and DPU 3760Hets, making it a broadly compatible switch across several machine families. When you order by part number, you can be confident you are receiving the correct switch for your application.
Key Features
- Genuine OEM Switching Accuracy — Manufactured to Wacker Neuson's original calibration threshold, ensuring the switch opens and closes at the correct pressure point for each supported machine.
- Direct Drop-In Replacement — Matches the original connector type and thread specification so the switch seats and wires in without rework or adapter fittings.
- Broad Cross-Family Fitment — Confirmed for HSH350 hydronic surface heaters, E1100 ground heaters, RD15 tandem rollers, and DPU 3050HE, DPU 3060HE-TS, DPU 3750Hets, and DPU 3760Hets reversible plate compactors.
- Engine Protection You Can Count On — A correctly functioning oil pressure switch triggers an immediate shutdown when oil pressure drops below the safe threshold, protecting the engine from internal damage caused by oil starvation.
- Electrical Safety Compliance — As a safety-critical shutdown component, using a genuine OEM switch ensures the trigger point and circuit behavior conform to the original design intent, keeping the protection system trustworthy.
The oil pressure switch monitors engine oil pressure in real time and sends a signal to the machine's control circuit when pressure falls below a safe operating level. When pressure drops too low — due to a failing oil pump, low oil level, or internal wear — the switch triggers an automatic engine shutdown, preventing catastrophic internal damage. A faulty or out-of-spec switch can either fail to shut the engine down when it should, leaving the engine unprotected, or cause nuisance shutdowns that interrupt work unnecessarily. Replacing a worn or failed switch with the correct OEM part restores the engine's protection system to full working order.
