Oil alert switch Greenstar for Honda GX110 GX140 GX160 Engine 21290

Description

Product Overview

The Greenstar oil alert switch is a precision‑engineered component designed specifically for Honda GX110, GX140 and GX160 small‑engine models. Constructed from high‑grade polymer housing and a corrosion‑resistant metal contact, the switch delivers reliable low‑oil detection while withstanding the harsh vibrations and temperature fluctuations typical of power tools and outdoor equipment. The part number 21290 aligns with the original manufacturer specification 15520‑ze1‑003, guaranteeing a perfect fit without the need for modifications or additional adapters. Its compact dimensions—measuring just 5.59 x 2.83 x 2.68 inches and weighing only 0.35 ounces—allow it to be installed in confined engine bays while maintaining full functionality. The switch operates on a simple on/off principle: when oil levels drop below the calibrated threshold, the internal sensor triggers an audible and visual warning, prompting immediate operator action to prevent engine damage. This proactive safety feature extends engine life, reduces downtime, and saves on costly repairs.

Usage

Designed for a wide range of applications, the Greenstar oil alert switch is ideal for both professional contractors and hobbyist users who rely on Honda-powered equipment for landscaping, construction, and maintenance tasks. Whether you are operating a power sander, a portable generator, or a small pump, the switch integrates seamlessly into the existing engine architecture, providing continuous monitoring during prolonged operation. Its quick‑connect terminals enable installation in under ten minutes, making it suitable for on‑site repairs where time is critical. The switch’s low‑oil alert function is especially valuable in environments where fuel quality may vary, or where operators may inadvertently overlook routine oil checks. By delivering an early warning, the switch helps prevent catastrophic engine seizure, ensuring that tools remain operational throughout the workday. The product is also compatible with aftermarket modifications, allowing users to upgrade older engines to meet modern safety standards without extensive re‑engineering.
