The Multiquip 1584139010 Oil Switch is a genuine OEM component designed for DAC7000SS series ultra-silent diesel generators, DLW and DAW series diesel welders, and the WRS5200DFPU ride-on roller screed. As a direct OEM replacement, this switch is sourced from Multiquip and built to the same specification as the original part your equipment left the factory with. Verified fitment includes the DAC7000SSA, DAC7000SSW, DAC7000SS, DLW330X2, DAW500SA4, DLW400ESA4, DLW400ES/ESA/ESA1, and WRS5200DFPU — confirm your model before ordering.
Key Features
- OEM-Accurate Switching Threshold — Calibrated to the correct oil pressure trigger point for Multiquip diesel-powered equipment, ensuring the switch opens and closes at the pressure levels your machine's engine management expects.
- Drop-In Replacement — Matches the original connector, thread pitch, and mounting configuration so installation requires no modification to the existing wiring harness or port.
- Broad Verified Fitment — Confirmed for DAC7000SS series ultra-silent generators, DLW and DAW series diesel welders, and the WRS5200DFPU roller screed across multiple model variants.
- Engine Protection When It Counts — A correctly functioning oil switch triggers shutdown before low oil pressure causes internal engine damage; a failed or incorrectly rated switch removes that protection entirely.
- Critical Safety Component — As part of the engine's oil pressure protection circuit, this switch is directly responsible for preventing costly engine seizure in the event of oil loss — correct specification is non-negotiable.
An oil switch — also known as an oil pressure switch — monitors the engine's oil pressure and signals the control system when pressure drops below a safe operating threshold. On diesel-powered generators, welders, and screeds like those in the DAC7000SS and DLW series, this switch is wired into the automatic shutdown or warning circuit, cutting power to the engine before dangerously low oil pressure can cause irreversible internal damage. When the switch fails or sticks, the engine loses its primary pressure-based protection, leaving it vulnerable to seizure during a low-oil event without any warning to the operator.
