Buying Guide
Key questions to consider when choosing a piggyback plug float switch:
- What is the pump’s amperage and voltage, and does the float switch meet or exceed that load?
- Is the cord length sufficient to reach from the pump to the power source without strain?
- Do you need waterproof or submersible performance (IP68), and is outdoor use a primary concern?
- Is a piggyback plug required for your current power setup, or would a universal replacement be more versatile?
