Multiquip 6002111940 Oil Pressure Switch DCA-800SSK/SA12V140

The Multiquip 6002111940 Oil Pressure Switch DCA-800SSK/SA12V140 is a genuine OEM oil pressure switch designed for the DCA800SSK and SA12V140 series generators. Sourced directly from Multiquip, this part matches the original component specification and drops into place without modification. It is confirmed to fit DCA800SSK and SA12V140 equipment, making it a straightforward service replacement for operators and technicians maintaining these units in the field or shop.

Key Features

• Genuine OEM Sensing Accuracy — Built to the original switching threshold spec, so the engine protection circuit responds at exactly the correct oil pressure level.
• Direct Connector Match — Replicates the OEM terminal and thread configuration for a clean, direct installation on DCA800SSK and SA12V140 generators.
• Confirmed Fitment — Verified for DCA800SSK and SA12V140 series units; verify your model before ordering to ensure compatibility.
• Engine Protection You Can Count On — A correctly functioning oil pressure switch safeguards the engine from low-oil damage; a failed switch can prevent start-up or allow the engine to run unprotected.
• Critical Safety Circuit Component — This switch is part of the engine shutdown safety system; using an OEM-spec part ensures the protection circuit operates within the designed parameters.

The oil pressure switch monitors engine oil pressure and sends a signal to the control circuit to either enable starting or trigger an automatic shutdown if pressure drops below a safe threshold. On generator sets like the DCA800SSK and SA12V140, this protection is essential — without a properly functioning switch, the engine has no automatic defense against oil starvation, which can lead to rapid internal damage. A faulty or worn switch may cause nuisance shutdowns, a no-start condition, or worse, allow the engine to run with dangerously low oil pressure.
