The Honda 31204-Z2E-003 Magnet Switch Assembly is a genuine OEM component designed for a wide range of Honda horizontal shaft engines, generators, and two-stage snow blowers, including GX240, GX270, GX340, GX390, and GX440 engines, EM4000, EM5000, and EM6500 generators, EU6500 and EU7000 inverter generators, and HS1336 and HSM1336 two-stage snow blowers. As a genuine Honda part, it is manufactured to the same specification as the original, ensuring a direct, hassle-free replacement. Because Honda revises parts at production serial breaks, verify your machine's serial number against the fitment table before ordering to confirm this is the correct assembly for your unit.
Key Features
- Genuine OEM Switching Performance — manufactured by Honda to the original electrical specification, so the switch actuates at the correct magnetic threshold and protects the starting circuit as intended.
- Broad Fitment Across Honda Lineups — covers GX240, GX270, GX340, GX390, and GX440 horizontal shaft engines; EM4000, EM5000, and EM6500 generators; EU6500 and EU7000 inverter generators; and HS1336 and HSM1336 two-stage snow blowers.
- Direct OEM Replacement — matches the original connector, housing geometry, and mounting configuration so this assembly drops in without alteration.
- Serial Number Awareness — Honda supersedes components at production breaks, so cross-check your unit's serial number with the fitment table to confirm part number 31204-Z2E-003 is correct for your specific machine.
- Starting Circuit Integrity — a failed or worn magnet switch can prevent the starter from engaging or cause erratic starting behavior; replacing it with this genuine assembly restores consistent, dependable start-up across all covered equipment.
The Magnet Switch Assembly is an electrically operated switch that uses a magnetic field — generated when the starter circuit is energized — to close a high-current contact and engage the starter motor. It acts as the bridge between the ignition key or start switch and the starter motor itself, handling the heavy current load that the control circuit alone cannot carry. When the magnet switch fails or its contacts burn or corrode, the starter motor receives no power and the engine or equipment will not crank; replacing this assembly restores proper starter engagement and gets the machine running again.
