Parts Desk Insights
Best Use Case: Ideal for replacing or upgrading an automatic bilge float switch where you want a covered float design that helps reduce false cycling from sloshing and debris.
Common Issues: Common service issues with float switches include debris fouling under/around the float cover, corrosion from prolonged moisture exposure, and wiring movement that can affect switch behavior—this style uses a sealed switch and a cover intended to help with those concerns. Inspect mating surfaces and check the switch movement for free travel during install, and verify wiring/connection integrity against your pump’s switch wiring diagram.
