T-H Marine Enclosed Bilge Pump Float Switch

T-H Marine’s enclosed float switch is designed to turn on a compatible bilge pump when water rises. It provides the water-level trigger that a nonautomatic bilge setup needs for automatic operation. It is intended for installation in a boat’s bilge, where water levels rise and fall during use. The enclosed layout keeps the switching mechanism within its housing.

When the water rises enough to move the float, the switch signals the pump to run. Once the level drops, the float returns and the automatic pump cycle can end. This arrangement reduces the need to watch the bilge constantly or manually start the pump for every ordinary water accumulation. It does not replace the pump itself or the need for a properly wired bilge system.

• Automatic water-level switching for a bilge pump
• Enclosed float mechanism
• For compatible marine bilge-pump systems
• Standalone switch; bilge pump sold separately

The float switch is only one component of the bilge system, so it must be matched to the pump and wiring it controls. Position the housing where the float can move freely without catching on nearby equipment or hoses. When replacing an older switch, compare the available space and electrical requirements before connecting it. Browse bilge pump switches and accessories for more automatic pump controls.
