Automatically Dry

As the water rises in your engine compartment, these switches turn on your bilge pump to keep you, your family, friends and boat safe. They are compatible with any brand of bilge pump and will make any bilge pump ready for fully automatic operation.

Attwood offers two types of automatic bilge pumps switches, their all-new digital series and their automatic float switch - the most popular float switch in boating history.

Digital Switches - Cutting Edge Engineering

Attwood's new digital bilge switch incorporates a proprietary Electronic Sensing technology to detect bilge water levels and trigger pump activation. They are engineered to operate in any bilge water mixture consistently without failure, so you can rest ensured that your pump won't be exposed to continuous cycling as the S3 switch won't be fooled by splashing bilge water, chemicals, sludge build up or foam.

Easier Installation

For added convenience, the Attwood digital bilge switch can be mounted on the floor of the bilge directly to a stringer wall or alongside the basket of the pump without added components or bracket - and the Attwood Digital bilge switch is directly compatible with all competitive products.

Five Year Warranty - Boating's Best

With an industry leading 5 year warranty, the Attwood digital bilge switch is built to last. It comes equipped with fully sealed electronics that are completely protected from water or chemical damage. More importantly, this switch is free of moving parts that can jam up, break or wear out over time.

Attwood Float Switches

Excellent engineering - like all Attwood boat parts

The most popular float switches in the history of boating. These Attwood automatic float switches feature a compact, low-profile design that mounts on any surface from horizontal up to a 24° angle.

• No large voltage drop which reduces bilge pump output like some reed switch designs.
• Incorporates a reliable and affordable mechanical switch that actuates pump motor at 2" water level.
• Wire leads do not flex or hinge with the float as on some competitive models.
• Integral cover dampens bilge sloshing to reduce pump cycling, and prevents debris interference.
• Sealed switch mechanism resists moisture, fume-ignition, and electrical shock.
• Maximum amp draw is 12 amps (at 12-Volts D.C.) or 6-amps (at 24-Volts D.C.).
• One Year Warranty
