Attwood Automatic Bilge Pump Switch

Attwood Automatic Bilge Pump Switch is a reliable float switch designed to automate your bilge pump and keep your boat dry even when you're not on board. When water in the bilge reaches the preset level (approximately 2 inches / 50 mm), the mechanical float activates the pump automatically. Once the water is removed, the switch turns the pump off again. Its compact design, protective cover, and built-in test function make it a practical choice for both new installations and upgrades of existing bilge systems. It’s a simple yet effective way to add automatic water control to your boat. Automatic bilge pumping without supervision The Attwood Automatic Bilge Pump Switch turns a standard bilge pump into a fully automatic system. The float mechanism responds directly to rising water levels, ensuring that unwanted water is removed without manual intervention. This helps protect your boat from rainwater, spray, and condensation buildup while it is docked or stored for extended periods. Protected design for marine environments The integrated protective cover reduces interference from debris, spray, and dirt, helping prevent false activations and improving long-term reliability. The sealed construction helps protect the internal mechanism from moisture and electrical issues, making it suitable for continuous marine use. Easy testing and installation A built-in test button allows you to verify pump operation without needing to flood the bilge, making maintenance quick and convenient. The low-profile design can be mounted on flat surfaces or up to a 24° angle. It can also be installed directly with Attwood V-Series bilge pumps for streamlined integration.
