Description
Overview:
This non-genuine Stop Switch (Oil Alert) is a replacement safety sensor for Honda small petrol engines, including the GX110 and GX160. It is built with a durable metal body and an insulated top with a single lead connection to withstand vibration and regular use on site. The switch monitors crankcase oil level and, when oil falls too low, it signals the ignition to cut out to protect the engine from damage. It is suitable for a wide range of compact engines found on construction and garden equipment such as generators, pumps, pressure washers, plate compactors, tillers, and mixers. Designed as a direct-fit replacement, it helps keep engines running reliably by preventing dry running and allows straightforward installation with basic tools.
Key Features:
- Non Genuine Part designed as a cost-effective replacement for the Honda oil alert switch
- Automatic low-oil shutdown to protect the engine from scoring or seizure
- Robust metal sensor body with insulated terminal for long service life in tough environments
- Direct-fit design for common Honda GX-series mounting points and wiring
- Simple single-wire connection for quick installation and troubleshooting
- Stable switching performance helps reduce nuisance cut-outs when oil level is correct
- Suitable for frequent start/stop duty typical of site and garden machinery
- Helps maintain compliance with best-practice safety routines on shared equipment
Typical Applications:
Used on small Honda-powered machinery including generators, water pumps, pressure washers, compactors/whackers, concrete mixers, tillers, lawn and turf equipment, and other plant using GX110-GX200 engines. Ideal for routine maintenance, engine rebuilds, or replacing a faulty oil alert that causes intermittent stalling or fails to protect the engine.
