The Wacker Neuson Stop Switch is a genuine OEM component designed for a wide range of Wacker Neuson BPU reversible vibratory plate compactors, BFS gasoline floor saws, and A-series gasoline power units for internal vibrators. As a direct factory replacement, this stop switch maintains the exact electrical characteristics required for safe, code-compliant engine shutdown across compatible equipment. It fits models including the BPU 2440A, BPU 2450A, BPU 2950A, BFS 80, BFS 100, A3000, and A5000, making it a versatile service part for contractors running mixed fleets. Sourcing a genuine Wacker Neuson part ensures the switch integrates correctly with the machine's ignition circuit without improvised wiring or fitment issues.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the exact resistance and switching characteristics specified by Wacker Neuson, ensuring consistent ignition cutoff performance every time.
- Drop-In Replacement — Matches the original connector and mounting footprint, so the switch seats and connects the same way as the part it replaces.
- Broad Fitment Across Multiple Machine Families — Compatible with BPU 2440A, BPU 2450A, BPU 2950A reversible vibratory plates, BFS 80 and BFS 100 gasoline floor saws, and A3000 and A5000 gasoline power units.
- Critical Shutdown Reliability — A functioning stop switch is the operator's primary means of cutting engine power; a worn or intermittent switch can leave the engine unable to shut down on demand.
- Safety-Critical Component — Engine stop switches are a core operator safety control; using the correct OEM part ensures the shutdown circuit meets the original design intent for the machine.
The stop switch provides the operator with direct control over engine shutdown by interrupting the ignition circuit when engaged. On equipment like vibratory plate compactors, floor saws, and internal vibrator power units, the ability to cut engine power instantly is essential for safe operation and machine handling. When the stop switch fails — whether through corrosion, physical damage, or electrical wear — the engine may become difficult or impossible to shut down through normal controls, creating a hazardous situation and halting productive work until the switch is replaced.
