Multiquip EM20150 Palm Handle with Switch Left

The Multiquip EM20150 Palm Handle with Switch Left is a genuine OEM replacement designed for HTX, STX, PRX, LD6, and HHX series ride-on power trowels. As a direct OEM component, the part is manufactured to the same specification as the original part, ensuring correct fitment and consistent switch operation across compatible machines. This handle is confirmed to fit a wide range of Whiteman hydrostatic and mechanical ride-on trowel models including HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX6H, STX55J6, STX55Y6, STXD6i, STXDF, HTX6H, HTXD6i, HTXG6DF, PRX, LD6, LD6SL, LD60, HHXD5, HHXG5, HHXDF4, and HHXDF5. When the operator handle or its integrated switch shows signs of wear, damage, or electrical failure, replacing it with a genuine OEM part keeps the machine operating as intended.

Key Features

• Genuine OEM Electrical Integrity — Built to the original switch resistance and contact spec, ensuring the handle's integrated switch triggers machine functions correctly without misfires or intermittent faults.
• Direct-Fit Replacement — Mounts to the left-side operator handle position using the original hardware configuration, requiring no rework to the mounting bracket or wiring harness.
• Broad Trowel Series Coverage — Compatible with HTX, STX, PRX, LD6, and HHX series ride-on trowels, covering both hydrostatic and mechanical Whiteman models across multiple engine configurations.
• Sustained Operator Control — A correctly functioning palm handle switch gives the operator precise, consistent command over trowel blade engagement; a worn or intermittent switch can cause unintended blade behavior on a live concrete pour.
• Operator Safety Relevance — The palm switch is a primary operator-control safety input on ride-on trowels; replacing a faulty switch with a genuine OEM part ensures the control circuit responds as the machine was designed to require.

The palm handle on a ride-on power trowel serves as the operator's primary left-hand control interface, housing the switch that activates or modulates key machine functions during finishing passes. The integrated switch completes an electrical circuit that the trowel's control system depends on for safe, responsive blade operation — a worn contact or cracked housing can introduce intermittent signal loss that is difficult to diagnose and costly on a time-sensitive pour. Replacing the EM20150 Palm Handle with Switch Left at the first sign of stiffness, play, or switch irregularity protects both the quality of the concrete finish and the reliability of the machine's control response.
