Rule Hi-Water Bilge Alarm with Non-Mercury Float Switch

The Rule Hi-Water Bilge Alarm with Non-Mercury Float Switch gives automatic control for a compatible bilge pump without using mercury. Its buoyant switching mechanism responds to rising bilge water and closes the pump circuit automatically, providing a dedicated control point for installations that use a non-automatic bilge pump.

Marine-grade wiring and a robust switch mechanism are designed for demanding bilge service. The removable base on SuperSwitch models simplifies access for inspection and cleaning while preserving the installed mounting position. This additional separation makes the component easier to inspect during routine bilge-system checks and helps keep the installation understandable for future service.

Confirm pump current draw, electrical-system voltage, fuse or breaker requirements, mounting height, wire routing, and unrestricted switch movement or sensing before installation. Keep the sensing area clear of debris and test automatic pump activation with water after wiring is complete. A bilge switch should be inspected regularly as part of the boat's pumping system.
