Rule-A-Matic Plus Float Switch for Bilge Pumps

The Rule Rule-A-Matic Plus Float Switch pairs a strong, fully integrated, impact-resistant cover with 14-gauge, highly abrasion-resistant marine-grade wire, protecting the switch mechanism from debris and jamming.

A built-in test feature lets the switch be checked without waiting for the bilge to actually fill, and it's rated for pumps drawing up to 20 amps, covering everything from a small standard bilge pump to a higher-draw heavy-duty unit.

Model 40A and 40FA versions of this switch now include a 2-year warranty, backing up the sealed, impact-resistant design with real coverage. See what else we carry in bilge pump switches and accessories.
