The Wacker Neuson Stop Switch is a genuine OEM component designed for the MP20 and MP12 Single Direction Plates. Sourced directly through Wacker Neuson's authorized parts program, this stop switch is manufactured to the same specifications as the original part fitted at the factory. It installs as a direct replacement on the MP20 () and MP12 () Single Direction Plate models, restoring full operator control functionality without modification. Keeping a verified OEM part number like on hand ensures your plate compactor is ready to run safely and correctly when you need it.
Key Features
- OEM-Correct Switching Specs — Manufactured to the original electrical switching tolerances required for dependable stop-circuit operation on Wacker Neuson plate compactors.
- Direct-Fit Replacement — Matches the original mounting position and wiring connection points on the MP20 and MP12, dropping in without cutting, splicing, or adapting.
- Confirmed Fitment — Verified for the MP20 Single Direction Plate (5000630379) and MP12 Single Direction Plate (5000630380).
- Restores Reliable Machine Shutdown — A worn or faulty stop switch can prevent the engine from shutting down on command; replacing it with part 5000408490 restores the operator's ability to stop the machine instantly.
- Critical Safety Component — The stop switch is a primary operator safety control; using a genuine OEM part ensures the shutdown circuit meets the original design intent and performs correctly under field conditions.
The stop switch is the operator's primary means of shutting down the engine on a plate compactor. When activated, it interrupts the ignition circuit, cutting power to the engine and bringing the machine to a stop. A failed or degraded stop switch can leave an operator unable to shut the machine down on demand — a serious safety concern on any compactor — or may cause nuisance shutdowns if the circuit becomes intermittent. Replacing a faulty switch promptly with the correct OEM part keeps the machine's safety controls functioning as designed.
