Key Features

• Genuine OEM Specification: — Manufactured to the exact pressure threshold and electrical output required by the RX1575 engine — not an approximation.
• Direct-Connect Replacement: — Matches the original connector, thread pitch, and mounting configuration for a straightforward swap with no adapter needed.
• Confirmed Fitment: — Verified for the Multiquip RX1575 walk-behind roller using OEM part number 11425039450.
• Engine Protection Integrity: — A correctly functioning oil pressure switch ensures the engine protection circuit responds accurately — a faulty switch can cause undetected low-oil conditions or nuisance shutdowns.
• Electrical Safety Compliance: — As part of the engine shutdown circuit, this switch must perform to spec to protect against engine damage from oil starvation — using the correct OEM part is essential for safe operation.

An oil pressure switch monitors the lubrication pressure inside the engine and signals the control system when pressure drops below a safe operating threshold. On a walk-behind roller like the RX1575, this switch is a critical safeguard — if oil pressure falls dangerously low, the switch triggers a shutdown to prevent engine damage. When the switch fails, it can either allow the engine to run unprotected during a low-oil event or cause false shutdowns that interrupt compaction work, making timely replacement important for both machine longevity and operational reliability.
