Rule-A-Matic Plus (model numbers: 40A, 40FA)

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

ECO Switch (model numbers: 39, 39-24)

The ECO Switch is an ecologically sound automatic bilge pump control switch. Featuring a non-mercury design, the pump operates with simple air pressure. As water rises in the bilge, air rises in the air tube that is attached to the switch. This air pressure activates the switch that controls the pump. There are no moving internal parts, as all wiring is out of the water, which means that there are no submerged electrical connections at all. Offering complete reliability and outstanding performance, the Rule ECO Switch offers a viable alternative to traditional float switches.

High Water Bilge Alarm (model numbers: 33ALA, 32ALA, 31ALA)

The Rule High Water Bilge Alarm consists of a non-mercury bilge pump float switch and an in-dash gauge that features both a visual and an audible 85 db alarm. This unit allows an unmanned compartment to be constantly monitored. For additional compartments, add additional switches. Complies with CFR 182.530 which requires a visual and audible alarm in each unmanned space on commercial vessels at least 26 ft. (7.9m) in length.
