The Multiquip 50469100 Oil Pressure Switch 2G40 is a genuine OEM component designed for RAMMAX walk-behind roller models, specifically the RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N ). As a direct Multiquip OEM part, 50469100 is manufactured to the same specification as the original switch installed at the factory, ensuring correct electrical behavior and a proper drop-in installation. DHS Equipment supplies this part with fitment accuracy as the priority — verify your serial number range against the fitment data above before ordering to confirm compatibility with your specific unit.
Key Features
- Genuine OEM Switching Accuracy — Built to the original pressure threshold specification for the 2G40 engine, so the switch opens and closes at the correct oil pressure values — not an approximation.
- Direct Connector Match — Matches the original wiring connector and thread spec of the host port, allowing straightforward installation without adapters or modification to the engine block.
- Serial-Number-Verified Fitment — Confirmed for RW1404MR units at S/N 326075 and up, and RW1504HF units up to S/N 1534188. Check your serial number plate before ordering.
- Protects Engine from Low-Pressure Damage — A correctly functioning oil pressure switch triggers the warning or shutdown circuit before low oil pressure can cause internal engine damage. A failed switch removes that protection entirely.
- Critical Safety Circuit Component — This switch is part of the engine protection system on your roller. Using a correctly rated OEM-spec switch ensures the warning and shutdown circuit responds as designed under real operating conditions.
The oil pressure switch monitors engine oil pressure and signals the machine's warning or shutdown system when pressure drops below a safe operating threshold. On walk-behind compaction rollers like the RW1404MR and RW1504HF, this switch acts as the first line of defense against engine seizure caused by low or lost oil pressure. When the switch fails — either stuck open or stuck closed — the engine either shuts down unnecessarily or, more critically, continues running without alerting the operator to a dangerous pressure loss, which can lead to costly internal engine damage.
