The Multiquip 11430 Switch Assembly Rider Spray Option is a genuine OEM component designed for Whiteman and international ride-on power trowel series, including JWN24, HHN, and HTN models. As a direct OEM replacement, part 11430 is manufactured to the same standards as the original, ensuring correct electrical function and a proper drop-in fit with the existing spray system wiring. This switch assembly is confirmed to fit JWN24HTCSL/HSCSL, EHHNK5, HHNG5, HTN28K, HTN27K, HHN34TVD, JTO series, HHN31V, and HTN Kohler/Onan/Honda trowels. Keeping this component in good working order ensures your rider spray option operates on demand, protecting the concrete finish and keeping blades running smoothly.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the original switching circuit spec, ensuring correct voltage handling and reliable contact closure for the rider spray system.
- Direct Plug-In Replacement — Matches the original connector and mounting configuration on the trowel's spray option circuit, allowing straightforward installation without rewiring.
- Broad Trowel Series Compatibility — Fits JWN24, HHN, HTN, and JTO series Whiteman ride-on power trowels, covering both mechanical and heavy-duty configurations.
- Maintains Spray System Control — A failed or corroded switch interrupts operator control of the curing compound or water spray, leading to uneven concrete finishing; this replacement restores full on/off function.
- Electrical Safety Assurance — OEM-sourced contacts and housing materials meet the original design requirements, reducing the risk of arcing or intermittent faults in the spray circuit.
The rider spray option switch assembly controls the activation of the onboard spray system found on equipped Whiteman ride-on power trowels. When triggered, it completes the circuit that delivers water or curing compound to the trowel blades and concrete surface, helping operators maintain proper moisture levels during finishing. When this switch fails — through corrosion, wear, or impact — the spray system becomes unresponsive, forcing the operator to stop work and potentially compromising the quality of the concrete finish.
