Description
Attwood Automatic Float Switch w/Cover | Boat Supply Store
This Attwood Automatic Float Switch converts manual bilge pump systems to fully automatic operation, ensuring critical water removal without constant monitoring. It reliably activates your pump motor at a precise 2" water level and operates on both 12V and 24V DC systems, handling up to 12A at 12V. The integral cover minimizes false activations due to sloshing and debris, making it ideal for offshore fishing vessels operating in dynamic Gulf Coast conditions.

Common Concerns Answered
I'm concerned the 36" wire lead might be too short for my installation. What are my options?
While the 36" wire lead is standard for many applications, extension wire and connectors suitable for marine environments are readily available to accommodate longer runs if necessary.
Are there common issues with the durability of this switch?
While most users report high reliability, a small number have noted premature failure. Proper installation and ensuring the switch is correctly sized for the bilge pump's amperage draw will significantly contribute to its longevity.
Is this switch robust enough for heavy bilge water conditions?
Yes, the integral cover is specifically designed to dampen bilge sloshing and prevent debris interference, contributing to its robustness in typical marine bilge environments.
Frequently Asked Questions
How does the Attwood Automatic Float Switch convert a bilge pump to automatic operation?
The float mechanism rises with the water level and, at a predetermined height (2 inches), mechanically actuates an internal switch, completing the circuit to power the bilge pump motor.
What is the maximum amp draw for the Attwood Automatic Float Switch?
The switch is rated for a maximum of 12 amps at 12V DC and 6 amps at 24V DC.
At what water level does the Attwood Automatic Float Switch activate the pump?
The pump is activated when the water level reaches 2 inches.
Can the Attwood Automatic Float Switch be mounted on an angled surface?
Yes, this float switch is designed to mount on surfaces ranging from horizontal up to a 24-degree angle.
Does the Attwood Automatic Float Switch contain mercury?
No, this Attwood Automatic Float Switch features mercury-free construction.
