Multiquip 3274 Kill Button Assembly

The Multiquip 3274 Kill Button Assembly is a genuine OEM component designed for HHNG5, HTX6H, and STX6H ride-on power trowels. As a direct Multiquip OEM part, the 3274 is built to the exact specification of the original, ensuring correct fitment and dependable operation on every use. Sourced through DHS Equipment, this assembly is the correct replacement for Whiteman ride-on power trowel operators who need a part they can trust. Verify your model code before ordering — this assembly is confirmed to fit the HHNG5, HTX6H, and STX6H series.

Key Features

• Genuine OEM Electrical Integrity — Manufactured to Multiquip's original circuit and switch specifications, ensuring the kill signal is clean, consistent, and correctly rated for the ignition system.
• Drop-In Fitment — Engineered to mount directly into the original operator control position with no modification to wiring harness or housing required.
• Confirmed Compatibility — Fits HHNG5, HTX6H, and STX6H Whiteman ride-on power trowels — check your model code to confirm before ordering.
• Operator Control Reliability — A properly functioning kill switch allows the operator to shut down the engine immediately and with confidence; a worn or intermittent assembly can result in delayed or failed shutoff.
• Critical Safety Component — The kill button is a primary emergency stop control on ride-on trowel equipment; using a correctly rated OEM assembly maintains the intended shutoff response under operating conditions.

The kill button assembly serves as the operator-activated engine shutoff switch on ride-on power trowels. When pressed, it interrupts the ignition circuit, cutting power to the engine and bringing the machine to a controlled stop. Over time, the internal contacts or button mechanism can wear, corrode, or fail, resulting in a switch that feels unresponsive, sticks, or no longer reliably cuts engine power — any of which compromises the operator's ability to stop the machine quickly when needed.
