The Genie 80278GT Oil Pressure Switch is a genuine OEM component designed for TML-4000 and TML-4000N light towers. As a direct OEM replacement, this switch is manufactured to the same specifications as the original part, ensuring correct fit and proper function in your machine. Cross-reference part number 80278GT against your unit's parts manual to confirm it is the correct switch for your serial range before ordering.
Key Features
- Genuine OEM Construction — Built to the original Genie specification, this switch meets the same dimensional and electrical tolerances as the part it replaces, with no guesswork on fit.
- Direct Drop-In Replacement — Engineered to install in the same location and connect to the same circuit as the original switch, keeping service time to a minimum.
- Verified Fitment — Confirmed for TML-4000 and TML-4000N Terex mobile light towers, two of the most widely deployed towable light tower models on the jobsite.
- Engine Protection Integrity — A functioning oil pressure switch monitors engine oil pressure and triggers a shutdown or warning when pressure falls outside a safe range, protecting the engine from damage caused by low oil pressure conditions.
- Operational Safety — On a light tower running unattended overnight, a correctly working oil pressure switch is a critical safeguard. A failed or bypassed switch removes the engine's ability to respond to a pressure loss, risking serious mechanical damage.
An oil pressure switch monitors engine oil pressure and sends a signal to the control system when pressure drops to an unsafe level, triggering a warning or automatic shutdown to protect the engine. On a towable light tower like the TML-4000 or TML-4000N, where the unit often runs for extended periods with minimal supervision, this protection is especially important. A worn or faulty switch may fail to signal a low-pressure condition — leaving the engine unprotected — or may trigger false shutdowns that interrupt operation; either way, replacing a suspect switch promptly with the correct OEM part is the right course of action.
