Product Overview

Float Switch
Part #: 4202-7

Convert your bilge pumps to fully automatic operation with the Attwood Automatic Float Switch. This reliable component allows for seamless pumping at low water levels, activating when the water reaches just 2 inches. Its low-profile design ensures it can mount on virtually any surface, accommodating angles up to 24 degrees.

The float switch features a sealed mechanism that protects against moisture and shocks. With a maximum amp draw of 12 amps for 12V systems or 6 amps for 24V systems, it’s both powerful and efficient. Plus, there’s no mercury, making it a safer option for the environment.

Make testing your pump easy with the convenient test knob included!
