Rule-A-Matic-Float Switches

The bilge pump empties the boat of water to prevent it from sinking. Normally, the crew manually turns on the pump. Installing a Rule-A-Matic float switch provides extra protection. The float switch detects when the water in the boat rises to a certain level, then automatically turns on the bilge pump. In this situation, the pump empties the water from the boat even if the crew is not aboard. Once the pump finishes emptying the water, the switch turns it off. Dependable Silver Tin Oxide contacts have replaced the mercury used in the previous generation of this switches.
