The Wacker Neuson Oil Press Switch, 20Psi, 1.4 Bar is a genuine OEM component designed for the LTN6L, LTN6LE, LTN6L-V, LTN6L-V S, LTC4L, and LTV6L series light towers. As a direct OEM replacement, this switch is manufactured to the same calibration and trip-point specification as the original part, ensuring your engine protection system responds exactly as intended. This part covers an exceptionally wide range of LTN6L configurations — including 50Hz, 60Hz, CE, Tier 4F, cold-weather, LED, and custom variants — making part number the correct choice across the full LTN6L product family.
Key Features
- Calibrated Trip Point: — Factory-set to open at 20Psi / 1.4 Bar, matching the engine's minimum safe oil pressure threshold for accurate shutdown activation.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this switch carries the same part specification as the original installed component — no substitutions or approximations.
- Broad LTN6L Family Coverage: — Confirmed fitment across LTN6L, LTN6LE, LTN6L-V, LTN6L-V S, LTC4L, LTC4L-P, and LTV6L light tower variants, spanning 50Hz and 60Hz, CE and non-CE, Tier 4F, cold-weather, and LED configurations.
- Engine Shutdown Protection: — A correctly functioning oil pressure switch triggers an immediate engine shutdown when oil pressure drops below the safe threshold, preventing catastrophic engine damage during operation.
- Electrical Safety Compliance: — As a safety-critical shutdown component, using the correct OEM-specified switch ensures the protection circuit operates within its designed parameters — critical for both equipment longevity and operator safety.
- Plug-and-Play Replacement: — Designed to connect directly to the existing engine harness and port on supported LTN6L-family engines, including Kohler (Lombardini) powered units.
An oil pressure switch is a safety-critical sensor that monitors engine oil pressure and triggers an automatic shutdown if pressure falls below a safe operating level — in this case, 20Psi / 1.4 Bar. On Wacker Neuson light towers, this switch is wired into the engine's protection circuit and acts as the first line of defense against low-oil-pressure conditions that would otherwise lead to rapid engine wear or seizure. When the switch fails or drifts out of calibration, the engine may either shut down unnecessarily under normal operating pressure, or — more dangerously — fail to shut down when a genuine low-pressure event occurs, leaving the engine unprotected.
