The switch automatically activates the bilge pump when the water level rises and switches it off once the water has been removed, helping maintain a dry bilge without manual operation.

This model features a built-in mercury-free micro switch, making it a safer and more environmentally friendly alternative to traditional mercury float switches. It is designed for compatibility with both 12V and 24V DC systems, allowing installation on a wide range of boats and bilge pump setups.

The compact and durable construction is suitable for installation in typical bilge environments and can be paired with most non-automatic bilge pumps.
