The Wacker Neuson is a genuine OEM Oil Pressure Switch designed for the LTN6K and LTN8K light tower series, including Tier 4 Final, Cold Weather, Kubota-powered, and 120/240V variants. Sourced directly from Wacker Neuson, this switch is the same component installed at the factory, ensuring correct fit and function across the full range of compatible models. Verified fitment covers the LTN6K, LTN6K-V, LTN6K-V S, LTN6K-LT, LTN8K, LTN8K-V, LTN8K-V S, and LTN8K-LT series.
Key Features
- OEM-Specified Switching Threshold — Calibrated to the exact pressure activation point required by Wacker Neuson engines, ensuring the switch opens and closes at the correct oil pressure level — not an approximation.
- Direct Connector Match — Plug-and-play replacement that connects to the existing engine harness without adapter fittings or terminal modification.
- Broad LTN Series Coverage — Fits LTN6K and LTN8K light towers across multiple configurations: standard, cold weather, Tier 4 Final, Kubota-powered, and 120/240V versions.
- Engine Protection You Can Count On — A properly functioning oil pressure switch is the engine's first line of defense against low-oil-pressure damage; a failed switch can allow the engine to run unprotected or trigger false shutdowns that halt your operation.
- Critical Safety Component — As part of the engine protection circuit, this switch triggers automatic shutdown when oil pressure drops below a safe threshold, preventing catastrophic engine failure on the jobsite.
The oil pressure switch monitors engine oil pressure and signals the control system when pressure drops below a safe operating level. When pressure falls outside the acceptable range, the switch triggers an alert or automatic engine shutdown, protecting internal engine components from damage caused by oil starvation. A faulty or failed oil pressure switch can either allow an under-pressured engine to keep running — risking serious mechanical damage — or cause nuisance shutdowns that interrupt normal operation, making prompt replacement essential for both engine longevity and uptime.
