The Wacker Neuson Float Switch High is a genuine OEM component designed for the APT4S, APT6S, APT8S, APT4T, APT6T, and APT8T pump series, including skid-mounted and trailer-mounted configurations with surge brake, electric brake, and cold weather options. As a factory-sourced part, the is built to the exact specification Wacker Neuson requires for correct high-level float detection in these pump systems. Fitment covers a broad range of APT series models, making this the right replacement whether you are running a standard skid unit or a cold weather trailer pump. Cross-reference your model number before ordering to confirm this is the correct switch position for your application.
Key Features
- Genuine OEM Sensing Accuracy — Manufactured to Wacker Neuson's exact switching threshold so the high-level float triggers at the correct fluid level every time.
- Direct Drop-In Replacement — Matches the original mounting interface and wiring connection of the factory switch, allowing straightforward installation without adapting hardware.
- Broad APT Series Coverage — Compatible with APT4S, APT6S, APT8S, APT4T, APT6T, and APT8T pumps, including skid, surge brake, electric brake, and cold weather variants.
- Protects Pump Operation — A functioning high float switch prevents the pump from running in conditions that can cause cavitation or dry-run damage; a failed switch removes that protection entirely.
- Electrical Safety Compliance — As an OEM-sourced electrical switching component, the 5200024553 meets the insulation and contact rating specifications required for safe operation in wet pump environments.
A float switch high is a liquid-level sensing device positioned in the pump system to detect when fluid reaches an upper threshold. When the float rises to that level, the switch sends a signal that can trigger an alarm, shut down the pump, or activate a control circuit — preventing overflow or protecting the pump from operating outside its designed parameters. When this switch fails, the pump loses its high-level protection, which can lead to uncontrolled fluid conditions, equipment damage, or unsafe operation.
