Rule SuperSwitch Non-Mercury Float Switch

The Rule SuperSwitch 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. Correct placement also helps the switch respond consistently without interference from hoses, wiring, or loose equipment.

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. Look through the rest of our bilge and water pumps.

• The switch activates a compatible pump as bilge water reaches the designed level.
• The design uses a non-mercury method for automatic pump control.
• Automatic activation reduces reliance on manual switching when water rises.
• Accessible installation makes periodic testing and cleaning easier.
