The Honda 36100-ZH9-V03 Engine Stop Switch Assembly (SDMO) is a genuine OEM component designed for the GX270 horizontal shaft engine. As an authentic Honda part, this switch assembly is manufactured to the same standard as the original, ensuring correct operation and a direct fit without adaptation. Confirm your engine's serial number against the fitment table before ordering, as Honda issues supersessions at defined serial breaks and this variant is specific to the SDMO configuration of the GX270.
Key Features
- Genuine OEM Shutdown Accuracy — built by Honda to deliver clean, positive ignition cutoff every time the stop switch is activated, with no guesswork about circuit compatibility
- SDMO Variant — the (SDMO) designation identifies this as the specific switch assembly for SDMO-configured GX270 engines; verify your configuration matches before purchasing
- Direct Replacement for GX270 Engines — fits GX270 horizontal shaft engines and installs in place of the original with no modification
- Check Serial Number — Honda supersedes switch assemblies at serial number breaks; cross-reference your engine serial against the fitment table to confirm this is the correct part for your unit
The engine stop switch assembly gives the operator a reliable means of cutting ignition to shut the engine down safely. When the switch is activated, it grounds the ignition circuit, interrupting the spark and bringing the engine to a stop. A worn or faulty stop switch can prevent the engine from shutting off on command or, in some failure modes, keep the engine from starting at all — making this a straightforward but operationally critical component to keep in working order.
