The Wacker Neuson Stop Switch is a genuine OEM component designed for the BFS gasoline floor saw series, BPU reversible vibratory plate compactors, and A-series gasoline power units for internal vibrators. As a direct OEM replacement, this switch is sourced from Wacker Neuson and matches the original part in form and function — no guesswork on compatibility. Verified fitment spans the BFS 80, BFS 100, BPU 2440A, BPU 2450A, BPU 2950A, BPU 2540A, A3000, and A5000 models. Keep a spare on hand and swap it out quickly when the original shows signs of wear or failure.
Key Features
- Genuine OEM Electrical Spec: — Sourced directly from Wacker Neuson, this stop switch meets the exact switching voltage and circuit-interrupt rating of the original — critical for consistent engine shutdown behavior.
- Direct Plug-In Replacement: — Matches the original connector configuration and mounting profile across all listed models, so installation requires no wiring modifications or adapter hardware.
- Broad Cross-Family Fitment: — Covers the BFS 80 and BFS 100 floor saws, BPU 2440A, BPU 2450A, BPU 2540A, and BPU 2950A reversible plate compactors, plus the A3000 and A5000 gasoline power units.
- Reliable Engine Kill Performance: — A properly functioning stop switch ensures the engine cuts out immediately on demand — a worn or corroded switch can cause delayed or failed shutdowns, leaving equipment running unintentionally.
- Operator Safety Critical: — The stop switch is the primary manual shutdown control on these machines. A failed switch compromises the operator's ability to halt the engine in an emergency, making timely replacement essential.
The stop switch is the electrical component that interrupts the ignition circuit to shut the engine down when the operator activates it. On gasoline-powered equipment like floor saws, plate compactors, and vibrator power units, it provides the primary means of controlled engine shutdown. When the switch fails — due to corrosion, mechanical wear, or a broken contact — the engine may not respond to the stop command, or may cut out unpredictably, both of which create unsafe operating conditions and interrupt work.
