Multiquip 3273 Kill Button Assembly

The Multiquip 3273 Kill Button Assembly is a genuine OEM component designed for HHNG5, STX6H, and HTX6H ride-on power trowels. As a direct Multiquip OEM part, the 3273 is manufactured to the exact specifications of the original component, ensuring a proper fit and consistent operation every time. This assembly is the correct replacement for operators and service technicians maintaining Whiteman ride-on power trowels in the field or shop. Confirm your model code before ordering to ensure accurate fitment.

Key Features

• Genuine OEM Electrical Integrity — Manufactured by Multiquip to match the original switch actuation feel, contact rating, and wiring interface of the factory-installed assembly.
• Direct-Mount Replacement — Mounts to the operator handle in the same position as the original, connecting to the existing wiring harness without alteration.
• Confirmed Fitment — Verified for use on HHNG5, STX6H, and HTX6H Whiteman ride-on power trowel models.
• Immediate Engine Shutdown — A properly functioning kill button assembly allows the operator to cut engine power instantly, which is critical during blade adjustments, emergency stops, and maintenance access.
• Operator Safety Function — The kill switch is a primary safety control on ride-on trowels; a worn or non-responsive assembly compromises the operator's ability to shut down the machine quickly and reliably.

The kill button assembly is the operator-accessible switch that cuts ignition or fuel to the engine, bringing the machine to an immediate stop. On ride-on power trowels like the HHNG5, STX6H, and HTX6H, this control is positioned for fast, one-handed activation and is one of the most frequently used safety features on the machine. When the assembly wears out, sticks, or fails to make proper electrical contact, the engine may not shut down on command — creating a serious hazard during normal operation and servicing.
