Rule 40FA Rule-A-Matic Plus with Shield and In-Line Fuse Holder

Adding a  fuse will prevent damage to both the pump and switch should an electrical problem occur.

Sleek and rugged, the Rule-A-Matic Plus float switch has a strong, fully integrated, impact-resistant cover that protects against debris and jamming.

It features 14 Gauge highly abrasive resistant marine grade wire and a built-in test feature.

Designed for pumps drawing up to 20 Amps, the 40FA includes a 2-year warranty.

A Standard bilge pump is designed to use a float switch to automatically turn the bilge pump on and off as required.

Ideally, a dash-mounted Rule 41 Automatic On-Off Toggle Switch can be used to provide Manual On/Automatic control of the pump and red light indication of operation

The Rule 40FA Float Switch offers outstanding performance.

Rule uses extra-large float chambers for increased buoyancy and detachable mounting bases that make them easier to install and remove for cleaning and inspection.

  • Suitable for pumps that draw up to 20 Amps
  • Voltage: 12, 24 or 32V DC
  • Dimensions:
    • L: 4-7/8" (124 mm)
    • W: 2-1/2" (64 mm)
    • H: 2-3/4" (70 mm)
