Rule 43 3 Way Bilge Pump Switch Panel - 12 Volt

The Rule 43 is a 12V, 20A three-way lighted rocker panel for controlling a bilge pump in automatic, off and momentary manual modes when used with a compatible automatic pump or float-switch system.

The Rule 43 provides dashboard control for a compatible 12V bilge-pump installation. The three-position lighted rocker allows the operator to leave the pump in automatic control, isolate the pump, or run it manually for testing and water removal.

Which Bilge-Pump Systems Is the Rule 43 Compatible With?

• For 12V DC systems only.
• Maximum switched current: 20A DC.
• Compatible with bilge pumps controlled by an external float switch or a suitable automatic pump circuit.
• The connected pump, switch, cable and fuse must all be correctly rated for the circuit.

What Do the Automatic, Off and Manual Positions Do?

Automatic allows a connected float switch to control the pump, Off interrupts normal pump operation, and Manual energises the pump directly while the momentary switch position is held. The panel does not provide water-level sensing by itself.

How Should the Switch Panel Be Selected?

Confirm all electrical and installation details before wiring:

• System voltage: 12V DC
• Maximum current: 20A DC
• Control positions: Automatic / Off / Manual
• Circuit protection: Use the fuse specified for the connected pump
• Panel cut-out / space: 73 x 60 mm (W x H)

Construction and Design

• Switch configuration: Three-way lighted rocker
• Control positions: Automatic / Off / Manual
• Circuit protection: Use the fuse specified for the connected pump
• Panel dimensions: 73 x 60 mm (W x H)

Installation and Safety

Install the panel in a dry, accessible dashboard location. Use marine-grade cable sized for the pump load and total cable run, fit the pump manufacturer’s specified fuse close to the power source, and follow the Rule wiring diagram. Confirm that automatic, off and manual functions operate correctly after installation.

Maintenance

Test all switch positions periodically and inspect the electrical circuit for corrosion, heat damage or loose connections.

• Confirm the correct fuse is fitted and serviceable.
• Keep the panel and rear terminals dry and protected.
• Check that Manual operates the pump and Automatic allows float-switch control.
• Replace a damaged, loose or unreliable switch panel.

Frequently Asked Questions

Can the Rule 43 be used on a 24V boat?
No. Model 43 is the 12V version. Use a panel switch specifically rated for 24V systems.

Does this switch make a standard pump automatic?
The panel alone does not sense water. A compatible float switch must be installed with a standard pump.

What do the three positions do?
Automatic leaves control to the float switch, off isolates the pump, and manual runs the pump while the manual control is held.
