Parts Desk Insights
Best Use Case: Ideal for replacing a mechanical float/older-style switch when you want a sealed, no-moving-parts electronic sensing design for bilge automation.
Common Issues: If your bilge pump cycles too frequently, confirm the switch mounting location and bilge water conditions, and inspect wiring and the fuse/connection points per the installation instructions. Also ensure the switch is oriented and installed so it can sense bilge water consistently.
