Engineered to consistently operate in any bilge water mixture without failure, Attwood's S3 Series automatic bilge switch includes electronic sensing technology to detect bilge water levels and trigger pump activation. S3 series switches can easily distinguish splashing bigle water, chemicals, sludge build-up or foam to ensure that the pump is not exposed to continuous cycling.

For added convenience, the bilge switch can be mounted directly on the floor of the bilge, directly to a stringer wall or alongside the basket of the pump without any added components or brackets. Electrical components are fully sealed so they are completely protected from water and chemical damage.

A five year warranty is included.
