DHS Equipment stocks genuine Multiquip parts to help you get your trowel back in service without guesswork.
Key Features
- Correct Electrical Specification — Matched to OEM resistance and connector spec for the kill switch circuit, ensuring the switch actuates and cuts ignition as intended.
- Drop-In Fitment — Engineered to route and connect exactly as the original assembly, with no splicing or adapter work required during installation.
- Confirmed Trowel Compatibility — Verified fit for HTN27K and HTN28K Whiteman mechanical ride-on power trowels.
- Ignition Kill Integrity — A functioning kill switch wire assembly is essential for the operator to shut down the machine immediately; a damaged or failed wire can prevent clean ignition cutoff.
- Operator Safety Critical — The kill switch circuit is a primary safety system on ride-on trowels; using a genuine OEM wire assembly maintains the integrity of that circuit under field conditions.
- Genuine Multiquip OEM Part — Carries the Multiquip OEM designation, backed by the same quality standards as the original production part.
The kill switch mechanical wire assembly connects the operator-accessible kill switch to the ignition system, completing the circuit that allows the engine to be shut down quickly and deliberately. On ride-on trowels like the HTN27K and HTN28K, this wire is routed through the machine frame and must maintain a reliable connection under the vibration and mechanical stress of troweling operations. When the wire assembly becomes damaged, corroded, or develops a break in continuity, the kill switch may fail to cut the engine or may cause intermittent shutdowns — both of which create hazardous operating conditions and unexpected downtime.
