Automatic Bilge Switch S3 SeriesPart #: 4801-7Incorporates a proprietary Electronic Sensing technology to detect bilge water levels and trigger pump activation and has been engineered to operate in any bilge water mixture consistently without failure. Your pump won't be exposed to continuous cycling as the S3 switch can easily distinguish splashing bilge water, chemicals, sludge build up or foam and comes equipped with fully sealed electronics that are completely protected from water or chemical damage. For added convenience, the 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 brackets. The S3 Series switch is also directly compatible with all competitive products and free of moving parts that can jam up, break or wear out over time.Features:
Attwood's S3 electronic bilge switch is the industry answer to broken mechanical switches, jammed float mechanisms and ever annoying excessively cycling pump. The S3 Series bilge pump switch incorporates a proprietary Solid State electronic Sensing Technology to detect bilge water levels and trigger pump activation more consistently, more reliably and for a significantly longer working life compared to traditional mechanical float switches.
Attwood has engineered the S3 series to operate in any bilge water mixture dependably, without failure. The S3's smart sensing system can distinguish bilge suds, gasoline or marine oil mixtures for bilge water and respond appropriately. With Attwood S3, you can rest assured that harmful chemicals, if spilled into the bilge, won't be pumped overboard. More importantly, the Attwood S3 won't be fooled by splashing waves or water moving across the bilge in a rocking boat. Excessive pump cycling is a problem of the past when using the Attwood S3.
