The Wacker Neuson Float Switch Low is a genuine OEM component designed for the APT4S, APT4T, APT6S, APT6T, APT8S, and APT8T series submersible trash pumps, including standard, surge brake, electric brake, and cold weather configurations. As a direct OEM replacement, this switch is manufactured to Wacker Neuson's exact electrical and mechanical specifications, ensuring consistent, dependable operation in the pump systems it controls. Compatibility spans the full APT pump lineup, covering both skid-mounted and trailer-mounted variants across all available brake and weather package options. Verify your model number against the fitment list to confirm the right part before ordering.
Key Features
- Correct Switching Threshold: — Genuine OEM construction ensures the float activates and deactivates at the precise liquid level required to protect pump operation.
- Direct Plug-In Replacement: — Engineered to match the original mounting configuration and wiring connection in Wacker Neuson APT series pumps, dropping in without modification.
- Broad APT Series Coverage: — Fits APT4S, APT4T, APT6S, APT6T, APT8S, and APT8T models, including cold weather, surge brake, and electric brake variants.
- Protects the Pump from Dry Running: — A correctly functioning float switch cuts power before the pump runs dry, preventing premature wear and internal damage to pump components.
- Electrical Safety Compliance: — As an OEM-sourced electrical switching component, this part meets the original design specifications for safe operation within the pump's control circuit.
- Genuine Wacker Neuson Part: — Sourced directly from Wacker Neuson, part number 5200024554 carries full OEM traceability for confidence in fitment and quality.
A float switch low monitors the liquid level inside or around the pump and signals the control system when that level drops below a safe operating threshold. In Wacker Neuson APT series pumps, this low-level signal triggers an automatic shutoff to prevent the pump from running dry — a condition that can rapidly overheat seals, damage impellers, and shorten pump life. When the float switch fails or sticks, the pump either shuts down unnecessarily or, worse, continues running without adequate fluid, leading to costly internal damage.
