Honda 36100-ZH8-W83 Engine Stop Switch Assembly (SDMO)

The Honda 36100-ZH8-W83 Engine Stop Switch Assembly (SDMO) is a genuine OEM component designed for GX160 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original switch it replaces, ensuring the electrical contacts, mounting geometry. This assembly carries the SDMO variant designation — confirm this matches your unit before ordering, as other switch variants exist for the GX160 platform.

Key Features

• Genuine Honda OEM Electrical Integrity — contact rating, wiring terminations, and switching action are held to Honda's original specification, so the stop circuit functions exactly as designed rather than approximated by an off-spec replacement.
• SDMO Variant — Match Before You Order — the SDMO designation identifies a specific version of the GX160 engine stop switch; verify your engine's configuration against part number 36100-ZH8-W83 and your serial number before purchasing.
• Direct OEM Replacement for GX160 Horizontal Shaft Engines — engineered to drop into the original mounting position without rework, restoring the stop circuit to proper operation.
• Serial Number Verification Recommended — Honda updates and supersedes switch assemblies at production breaks; cross-check your engine's serial number against the fitment table to confirm this is the correct assembly for your unit.

The engine stop switch assembly is the primary operator-controlled circuit breaker between the ignition system and ground. When the operator activates the stop control, the switch grounds the ignition circuit, cutting the spark and bringing the engine to a halt in a controlled manner. A switch that is worn, corroded, or electrically intermittent can cause hard-starting, unexpected shutdowns, or — critically — a loss of the ability to stop the engine on demand; replacing it with a correct OEM assembly restores dependable, predictable stop-circuit behavior.
