Key Features

• Genuine OEM Switching Mechanism: — Built to the exact trigger threshold and float travel specifications of the original, ensuring the pump shuts off at the correct water level every time.
• Direct Drop-In Replacement: — Matches the original mounting connection and float arm configuration on ST1 and ST1F submersible pumps for a straightforward installation.
• Confirmed Fitment: — Verified for Multiquip ST1 and ST1F submersible pump models.
• Automatic Pump Protection: — Cuts power to the motor when water drops below the activation threshold, preventing dry-run damage that can burn out the pump motor prematurely.
• Electrical Safety Compliance: — As an OEM-sourced switching component, this float switch meets the original electrical ratings for safe operation in wet submersible environments.

A mechanical float switch is the automatic shutoff guardian of a submersible pump. As the water level drops, the float arm descends with it and mechanically triggers the switch to cut power to the pump motor before it runs dry. Running a submersible pump without water — even briefly — can overheat and seize the motor, leading to costly repairs or full pump replacement. When the float switch fails or becomes stuck, the pump loses this protection entirely, making a timely replacement critical to keeping the unit operational and protected.
